AB  - Thermal properties of acrylate-based composite combined with alumina-based particles were investigated. The composites were made of poly (methyl methacrylate) (PMMA) modified with dimethyl itaconate (DMI) as a matrix. Neat alumina particles (Al2O3) and alumina doped with iron oxide (Al2O3-Fe) modified with 3-aminopropyl-trimethoxylane (AM) and flax oil fatty acid methyl esters (biodiesel - BD) were used as reinforcement. Thermal conductivity measurements showed that composite with alumina particles with the highest alpha phase content had the highest thermal conductivity values. Mechanical properties (tensile strength, modulus of elasticity and elongation at break) were improved by the addition of modified alumina particles to PMMA/DMI matrix. The thermal properties are the most improved for composite with 3 wt.% Al2O3-Fe-AM particles that had the lowest temperature in a crack zone was noticed (10.28 %) compared to PMMA added due to the better stiffness and highest thermal conductivity.

AB  - Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting and electrospinning. FESEM analysis revealed that the processing with electrospinning enables better dispersion of quantum dots. Time-resolved laser induced fluorescence measurements confirmed uniform size of QDs in fibers with the emission at only one wavelength. Oxidation effects in quantum dots were removed with the use of PMMA as a host, and the core remained active, which was confirmed with FTIR analysis and time-resolved laser induced fluorescence measurements.

AB  - The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic material, ZnS, has the cubic structure and its crystallite size was estimated to be 2.3 nm, which implies that a strong confinement regime is in effect. Analysis of Raman spectra was performed using the fitting procedure based on effective medium theory. As a result, the surface optical phonon (SOP) mode was detected. It was found that the shape and position of the SOP mode depend on the type of the composite.

AB  - Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with (3-aminopropyl)trimethoxysilane (AM) and methyl esters of linseed oil fatty acids (biodiesel-BD) were used as reinforcement. The mechanical properties of the prepared composites, containing 1, 3 and 5 wt% of surface-modified alumina particles, are compared to a neat polymer matrix. The particles were characterized by single-beam Fourier transform infrared spectroscopy, thermogravimetry and differential scanning calorimetry. The mechanical properties of the composites were determined by micro-Vickers hardness and impact testing. The morphology of the surface of the composites exposed to cavitation was observed through a field emission scanning electron microscope. AFM analysis was used to compare surface features seen using the SEM and to interpret the surface degradation properties. The hardness, cavitation resistance and high-impact energy resistance of the composites are better in the case of AM surface modification of alumina fillers, but biodiesel modified particles have comparable mechanical properties and a stabilized Al-O-Si bond that could be important when a composite is exposed to humidity or a wet environment.

AB  - Basalt as a filler in a polymer-based composite material fulfils the demand of being natural, environment-friendly material for the production of various composite materials. The material could be used as protective layer and the abrasion should be tested in order to evaluate the properties of the material. The cavitation test enables the evaluation of the possible service in conditions that simulate the extensive erosion. The presence of basalt in the matrix improves the resistance to cavitation. The possibility to further improve the material could be obtained using the reinforcement of the matrix itself by incorporation of submicron ceramic particles into the composite. The obtained hybrid composite material with the addition of reinforcement in the matrix further improves the cavitation resistance.

AB  - The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermo-mechanical properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite since acrylic materials lack of this feature. So, a good balance between hardness/toughness and transparency is obtained with the addition of poly (vinyl butyral) (PVB) and titania (TiO2) nanofibers simultaneously and controlling their contents. Specifically, when compared to that of pure acrylic polymer, the fracture toughness of the PMMA nanocomposite apparently increased 55% with the addition of 3 wt.% titania nanoparticles, while the produced nanocomposite maintained high transmittance above 75-80% in the visible domain. The transmission spectrum modelling of the reinforced fiber materials and hybrid acrylic composites using Mie scattering theory for different particle sizes and particle content is presented. The calculated transmission coefficients versus wavelength are compared with the experimental ones.

AB  - This research considers a possibility of improving the impact and ballistic resistance of composite materials based on aramid fabric impregnated with poly (vinyl butyral), PVB, with the application of multi-layer inorganic nanotubes of tungsten disulfide (INT-WS2) as the reinforcement. Multi-layered nano-structures of tungsten disulfide are known by their excellent mechanical resistance, especially shock absorbing properties, which promote their use as a reinforcement in composite materials. INT-WS2 used in this research were observed using scanning electron microscope and the obtained images were analyzed in program Image Pro Plus. Before the application in the composite they were ultrasonically deagglomerated. Ballistic composites were prepared impregnating the aramid fabric with system PVB/INT-WS2 and by pressing defined number of layers under high pressure and defined temperature. Charpy impact test, ballistic shooting with two different ammunition calibers and stab resistance test with controlled knife penetration were performed on prepared composite samples, and resulted in significant improvements for samples with nano-reinforcement regarding the absorbed energy of impact, toughness and the ballistic resistance.

AB  - Commercial gamma - Al2O3 particles, Al2O3 n, and synthesized Al2O3 doped with iron oxide (Al2O3 Fe) were used as reinforcements to enhance the toughness of an unsaturated polyester resin (UPR). Alumina modification with vinyl, Al2O3 (n, Fe)-VT, and methacryloyl, Al2O3 (n, Fe)-ME functionalities contributed to the increase in the extent of covalent binding at the UPR/filler interface. Tensile tests showed a slight improvement in the toughness of UPR/Al2O3 Fe composite and a significant improvement for the UPR/Al2O3 Fe-VT composite at a 1.0 wt.% particle loading. An enhancement in the micro Vickers hardness for UPR/Al2O3 Fe-VT and improved DMA properties were also evidenced.

AB  - The adsorption performance of three-dimensionally ordered macroporous (3DOM) alumina doped with iron oxide, and subsequently modified with (3-aminopropyl)triethoxysilane (APTES), FeAl2O3 and FeAl(2)O(3)APTES, was used for enhanced Pb2+, Cd2+ and Ni2+ removal. The phase composition and the structural and surface/textural properties of the obtained adsorbents were analyzed by X-ray diffraction analysis, field emission scanning electron microscope, energy dispersive X-ray analysis, thermogravimetry, Fourier-transfer infrared spectroscopy, specific surface area of the samples and point of zero charge determination. Adsorption of selected cations was examined in the batch conditions using different contact time, adsorbent dosage and temperatures. Different models of the adsorption isotherms were used for determination of the adsorption capacities, in which the best fit of Freundlich and Langmuir model was obtained for FeAl2O3, that is, Freundlich model for FeAl(2)O(3)APTES. A significant increase of adsorption capacities: from 44.21 to 51.66 mg g(-1) for Pb2+, 25.69 to 32.96 mg g(-1) for Cd2+ and 19.48 to 24.64 mg g(-1) for Ni2+ was obtained for FeAl2O3 and FeAl(2)O(3)APTES, respectively, which indicated the significance of the macroporous structure of 3DOM alumina and subsequent amino-terminal modification. The values of the correlation coefficient (R-2) suggested that pseudo-second kinetic model best describes Pb2+, Cd2+ and Ni2+ adsorption on FeAl(2)O(3)APTES, and Cd2+ and Ni2+ onto FeAl2O3, while second kinetic model gave the highest correlation coefficients for Pb2+ adsorption on FeAl2O3.

AB  - Poly(ethylene-co-vinyl acetate) (EVA) and poly(methyl methacrylate) (PMMA) are two incompatible polymers. Compatibilization of EVA/PMMA polymer blends with EVA-g-PMMA decreased the pore diameter and improved the mechanical properties. Image analysis of SEM micrographs enabled statistical analysis of the porosity parameters, including data about their positions. Positioning of the pores on the image was achieved by implementation of Voronoi diagrams and Delaunay triangulation by Python libraries. Hausdorff dimension (DHf) analysis showed improved complexity of the material network obtained by compatibilization. The coordinates of pore contours were processed by the Ramer-Douglas-Peucker algorithm (RDP) to establish the models by the finite element method (FEM). This process is iterative and enables a parametric study of the problem so that the type of pore geometry responsible for the observed mechanical behavior could be revealed. The FEM revealed the regions of the material that bear the load and enabled the extraction of parts of the material that diminish the porosity but do not participate in load carrying. A parametric study showed a decrease of 22% in the maximal shear stress when the porosity increased 10%, suggesting the importance of bulging of the material that played the role in decreasing the porosity of non-bearing material. A procedure for selecting the model with a regular pore shape and distribution based on the actual (irregular) porous microstructure is proposed.

AB  - Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different types of reinforcement of chemically very similar compositions, but different size and morphologies. In order to monitor the mechanical properties of the composite material, samples were made in the form of discs of defined dimensions suitable for polymerization under UV light. The subject of this study is the examination of the mechanical properties of the Bis-GMA (Bisphenol A glycidyl methacrylate)/TEGDMA (trimethylene glycol dimethacrylate) photopolymer composite material as a matrix. The reinforcements were in the form of commercial nanoparticles and alumina whiskers and their influence on mechanical properties were compared with the influence of synthesized alumina particles doped with iron oxide synthesized sol-gel technique. In order to test the mechanical properties of composite materials, the Brazilian Tests and the testing of the microhardness of samples were employed.

AB  - The focus of this doctoral dissertation is the preparation and characterization of wood-plastic composites (WPC), whereby a new method of obtaining hybrid polymer composites based on wood from solution and forming the final composite by a subsequent unconventional method of thermal processing and pressing is presented. During the workmanship of this doctoral dissertation, the possibilities of synthesis and incorporation of polyethylene teraphthalate (PET) fibers and aluminum oxide (Al2O3) particles in composite materials with a polymeric matrix based on wood were investigated. By adjusting the percentage content of PET fibers and Al2O3 particles during processing, it is possible to influence the mechanical properties of hybrid composites. Poly (methylmethacrylate) (PMMA) was used as the polymer matrix. Based on a detailed literature review, it has been concluded that there is a possibility of modifying wood fibers and polymer matrix by bonding agents (3-mercaptopropyl) trimethoxysilane (MPTMS) and 2,4-toluene diisocyanate (TDI). Also, the polymer matrix acts as a wood fiber impregnator, which is certainly due to the influence of the bonding agents and does not allow the water absorption. The combination of PMMA/wood surface modification and MPET fiber reinforcement (mixture of commercially available and recycled PET in a ratio of 1: 1) and modified Al2O3 particles (MPTMS) in a small percentage (up to 3 wt%) results in composites with advanced mechanical properties and water absorption properties and offers a new way to use recycled PET flakes, and provides the opportunity for further development of incorporation of alumina particles. In order to identify incorporated reinforcements in composites, various analyses were performed, such as scanning electron microscope (FESEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction analysis (XRD). These analyses have shown that fibers and particles are well dispersed during the composite processing. In addition, the resistance to moist absorption resistance of the composite was tested. Based on the obtained results, it is concluded that due to well dispersed MPET fibers and Al2O3 particles in the hybrid sample and the realized bonds between the modified particles and the sample, the water absorption was the smallest and amounted to only 1 wt%.
AB  - Fokus ove doktorske disertacije je na pripremi i karakterizaciji drvo-plastičnih kompozita (WPC), pri čemu je predstavljen nov način dobijana hibridnih polimernih kompozita na bazi drveta iz rastvora i formiranje finalnog kompozita naknadnom nekonvencionalnom metodom termičke obrade- presovanjem. U toku izrade ove doktorske disertacije istražene su mogućnosti sinteze i ugradnje različitih polietilen teraftalat (PET) vlakana i aluminijum oksid (Al2O3) čestica u kompozitne materijale sa polimernom matricom na bazi drveta. Podešavanjem procentualnog sadržaja PET vlakana i čestica Al2O3 prilikom procesiranja, moguće je uticati na mehanička svojstva hibridnih kompozita. Kao polimerna matrica korišćen je poli(metilmetakrilat) (PMMA). Na osnovu detaljnog literaturnog pregleda zaključeno je da postoji mogućnost modifikacije drvnih vlakana i polimerne matrice vezujućim agensima (3-merkaptopropil) trimetoksisilanom (MPTMS) i 2,4-toluen diizocijanatom (TDI). Takođe, polimerna matrica se ponaša kao impregnator drvenih vlakana, što je svakako posledica uticaja vezujućih agensa i ne dozvoljava apsorpciju vode. Kombinacija modifikacije površine PMMA/drvo i ojačanje u vidu MPET vlakana (mešavina komercijalno dostupnog i recikliranog PET u odnosu 1:1) i modifikovanih čestica Al2O3 (MPTMS) u malom masenom procentu (do 3 mas%) rezultuje kompozitima sa naprednim mehaničkim svojstvima i svojstima upijanja vode i nudi nov način za upotrebu recikliranih PET ljuspica, i daje mogućnost daljim razvojem inkorporiranja česticama aluminijum oksida. Sa ciljem identifikacije inkorporiranih ojačanja u kompozite, izvršene su različite analize, kao što su skenirajuća elektronska mikroskopija (FESEM), infracrvena spektroskopija sa Furijeovom transformacijom (FTIR) i rendgensko-difraktometrijska analiza (XRD). Navedene analize su pokazale da su vlakna i čestice dobro dispergovani tokom procesiranja kompozita. Pored toga, ispitana je efikasnost rezistentnosti na apsorpciju vlage kompozita. Na osnovu dobijenih rezultata zaključuje se da je zbog dobro dispergovanih MPET vlakna i čestica Al2O3 u hibridnom uzorku i ostvarenih veza između modifikovanih čestica i uzorka, apsorpcija vode najmanja i iznosila je svega 1 mas%.

AB  - Hybrid composite panels of Wood-Plastic Composites (WPC) consisting of wood and poly (methyl methacrylate) (PMMA) were reinforced with alumina particles and made by "hot pressing" method. Alumina-based particles were made by sol-gel technique. The particles were characterized by the X-ray diffraction (XRD). The resulting alumina particles were modified with (3mercaptopropyl) trimethoxysilane (MPTMS), in order to obtain better mechanical properties of the composite relative to the composite with unmodified alumina particles. The aim of this work was to study the influence of composite structure and the moisture absorption on bending and the impact properties of the hybrid composite. The bending and impact tests revealed that modulus of elasticity and absorbed energy of deformation increased with modification of alumina and slightly decrease after moisture absorption.

AB  - Composites are materials that reach many users and therefore, it is necessary to correlate the properties of every component on the behaviour of the material. Alumina is used as reinforcement with the aim of improving hardness. It was proven that the hardness depends on the crystal structure of the reinforcement. As the hardness is related to cavitation resistance, the influence of different reinforcements on the composite cavitation resistance was studied. Alumina and iron(III) oxide doped alumina particles were prepared by the sol-gel technique, starting from soluble salts of both elements. The gels were calcined at three different temperatures: 700, 800 and 900 degrees C. Poly(methyl methacrylate), PMMA, was used as the polymer matrix reinforced with alumina particles. The reinforcement content of all the samples was 3 wt %. Cavitation erosion of the samples was measured using a standard ultrasonic vibratory setup with a stationary sample. The cavitation resistance of the samples was studied using the classical mass loss method and the surface defects resulting from cavitation were analyzed. The morphologies of the defects after 1 h of cavitation erosion were examined by field emission scanning electron microscopy (FE-SEM). The images were characterized using the image analysis procedure. The results showed that the alumina crystal structure resulting at different calcination temperatures influences the defect morphology, cavitation resistance and the hardness of the composites.

AB  - PMMA poly(methyl methacrylate) has a large spectrum of uses as bone cements, in dentistry as denture base materials and other industrial applications. One of the main drawbacks of these materials is the residual monomer that is proven allergen and irritant. It was shown that addition of dimethyl itaconate (DMI) to the PMMA denture base systems decrease the quantity of residual monomer but, also deteriorate mechanical properties. The addition of alumina fillers in the PMMA/DMI produced composite materials results in improved mechanical properties compared with pure PMMA and additionally reduces the level of residual monomer in the composition.

AB  - Processing and characterization of polymer nanocomposites based on poly (methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots (QD's) were presented in this work. The aim is to preserve the optical activity of QD's in nanocomposite processing with improved mechanical properties. The modification of QD's CdSe/ZnS-PMMA interface was achieved with 3-mercaptopropyltrimethoxysilane (MPTMS). Nanocomposites were processed by solution casting. The samples of pure PMMA, and composites with unmodified and silane modified QD's CdSe/ZnS were processed. FTIR analysis revealed modification of QD's with silane and characteristic bonding with PMMA matrix. Raman spectrum confirms a presence of alloyed layer at the core-shell interface. Time-resolved laser induced fluorescence measurements confirmed slight blue shift in QD's CdSe/ZnS-PMMA composite without interface modification, while there was a slight red shift with modified particles. Oxidation effects in quantum dots were removed with the use of PMMA as a host, and the core remained active, which was confirmed with FTIR analysis and time-resolved laser induced fluorescence measurements.

AB  - Copper coatings are produced on silicon wafer by electrodeposition (ED) for various cathode current densities. The resulting composite systems consist of 10 mu m monolavered copper films electrodeposited from sulphate bath on Si wafers with sputtered layers of Cr/Au. Hardness measurements were performed to evaluate properties of the composites. The composite hardness (H-c) was characterized using Vickers microindentation test. Then, an artificial neural network (ANN) model was used to study the relationship between the parameters of metallic composite and their hardness. Two experimental values: applied load during indentation test and current density during the ED process were used as the inputs to the neural network. Finally, the results of the composite hardness (experimental and predicted) were used to estimate the film hardness (H-f) of copper for each variations of the current density. This article shows that ANN is an useful tool in modeling composite hardness change with variation of experimental parameters predicting hardness change of composite Si/Cu with average error of 6 %. Using created ANN model it is possible to predict microhardness of Cu film for current density or indentation load for which we do not have experimental data.

AB  - Composite systems of monolayer and multilayer nickel films electrochemically deposited on single crystal (100)-oriented silicon wafers were fabricated with and without the ultrasonic agitation. The hardness and adhesion behaviour of these composite structures were characterized by Vickers microindentation test. The dependence of composite microhardness and film adhesion on the structure of the film and mixing conditions of electrolyte were analysed. Mathematical models of Chicot-Lesage and Chen-Gao were applied to experimental data in order to obtain the film hardness and adhesion parameter respectively. It is confirmed that the mechanical properties of composite systems of nickel thin films on silicon substrate can be enhanced by formation of multilayer film structure by ultrasound-assisted electro-deposition and by reducing the layer thickness in the multilayer film.

AB  - Two-step synthesis of Fe2O3 particles, performed by precipitation from iron(III) chloride (FeCl3 center dot 6H(2)O) using ammonium hydroxide in first step and calcination at 400 and 700 degrees C during 4 h, provided Fe2O3 400 degrees C and Fe2O3 700 degrees C photocatalysts, respectively. The electrospinning process was used to prepare iron oxide fibers, named Fe2O3 fiber. Morphological and structural properties of samples were determined by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Fourier Transform Infra-Red (FT-IR) and BET/BJH analysis. It was found that the alpha-Fe2O3 phase (hematite) has shown the compaction of the structure at 700 degrees C, i.e. lower textural properties. Hematite particles and fibers are used for bisphenol A (BPA) removal by photocatalytic decomposition and the enhanced catalytic performance was found with the use of Fe2O3 400 degrees C particles.

AB  - A facile synthesis was employed for three polyhedral oligo silsequioxanes (POSS), obtaining incompletely condensed structures with fern-like and cubic morphologies. Proton nuclear magnetic resonance spectroscopy (H-1 NMR) indicated the successful synthesis of the proposed POSS structures. The hydroxyl groups affected the manner and type of POSS morphology, as seen under a scanning electron microscope (SEM) and a transmission electron microscope (TEM). Fourier-transform infrared spectroscopy (FTIR) showed the availability of surface hydroxyl groups that contributed to the formation of a higher amount of char residue, as found from TGA analysis. The highest decomposition temperature (281 degrees C) and the least char residue were found for a cross-linkable POSS, obtained by esterification of the hydroxyl groups with methacryloyl chloride.

abstract = "A facile synthesis was employed for three polyhedral oligo silsequioxanes (POSS), obtaining incompletely condensed structures with fern-like and cubic morphologies. Proton nuclear magnetic resonance spectroscopy (H-1 NMR) indicated the successful synthesis of the proposed POSS structures. The hydroxyl groups affected the manner and type of POSS morphology, as seen under a scanning electron microscope (SEM) and a transmission electron microscope (TEM). Fourier-transform infrared spectroscopy (FTIR) showed the availability of surface hydroxyl groups that contributed to the formation of a higher amount of char residue, as found from TGA analysis. The highest decomposition temperature (281 degrees C) and the least char residue were found for a cross-linkable POSS, obtained by esterification of the hydroxyl groups with methacryloyl chloride.",
