AB  - The objective of this study was to investigate the influence of polyhedral oligomeric silsesquioxane (POSS) structure on the adhesion behaviour of composite films onto a metallic surface. The composite films consisted of UV cured bisphenol A glycidylmethacrylate/triethylene glycol dimethacrylate (Bis-GMA/TEGDMA) as matrix and reactive POSS structures as adhesion enhancers. Composites were made with 1, 3 and 5 wt % of POSS. Adhesion was evaluated using the micro Vickers hardness testing method. The contact angle of composite films to a brass substrate was measured and compared to the adhesion parameter obtained from microhardness measurements. Optical microscopy indicated morphological segregation in the hybrid films suggesting the compatibility extent between the matrix and each particle. The shape and size of the indent were analyzed and correlated with adhesion quality. The methods used for the estimation of adhesion strength and quality clearly indicated that the highest adhesion enhancement of the Bis-GMA/TEGDMA matrix was POSS reagent containing both polar (hydroxyl) and nonpolar (unsaturated aliphatic - allyl) side groups.

AB  - The objective of this study is to investigate the influence of the polyhedral oligo silsesquioxanes (POSS) structure on cavitation erosion of hybrid acrylate composite films. Cavitation is used as a method for estimation of adhesion quality of a composite film on a metal substrate. The hybrid composite films consist of UV cured Bisphenol A glycidyl methacrylate/triethylene glycol dimethacrylate (BisGMA/TEGDMA) as matrix and reactive POSS structures as adhesion enhancers. POSS structure is established in dependence of content of hydroxyl groups and cross-linkable functionalities that affect the system compatibility. Composites are made with 1, 3, and 5 wt. % of three different types of POSS reagents containing: i) hydroxyl groups (POSS-M), ii) both hydroxyl and allyl groups (POSS-M-A), and iii) methacrylate groups (POSS-M-Cl). Morphology of composite films is examined by scanning electron microscope (SEM) and atomic force microscopy (AFM). The roughness after cavitation erosion of hybrid films with POSS-M-A determined by AFM was decreased for ~86% when compared to the polymer matrix. The loss of mass after cavitation erosion is significantly reduced by the addition of 5 wt. % of POSS particles. The best resistance to cavitation evaluated as the mass loss has a composite film with POSS-M-A particles and it exhibits ~94% lower mass loss when compared to the neat polymer matrix. Likewise, hybrid composite films with POSS-M-Cl and POSS-M particles decreased mass loss after cavitation test by
~91% and ~89%, respectively. The results indicate that improved mechanical properties and enhanced adhesion to the metal substrate contributed to improved resistance to cavitation erosion. Methods used in this study for estimation of adhesion quality and wear resistance clearly indicate that the best compatibility with BisGMA/TEGDMA matrix is achieved with POSS reagent containing both hydroxyl and allyl functional group.

AB  - Production of rubber plasticizers, based on waste poly(ethylene terephthalate) (PET), and economic effectiveness of developed technologies are presented and discussed. Waste PET glycolyzates, named diisononyl terephthalate(DINTP), didecyl terephthalate (DDTP), dibenzyl terephthalate(DBTP) and diglyceryl terephthalate(DGTP), were obtained by catalytic depolymerization of PET with isononyl alcohol, decyl alcohol, benzyl alcohol and glycerol. The structural analysis of the synthesized plasticizers was done using elemental, FTIR and NMR spectral analysis. Physical-mechanical properties of the rubber products composed of 100 phr of 28 % nitrile butadiene caoutchouc (NBR) and 20.7 phr of plasticizer were investigated. Influence of the synthesized plasticizers on Shore hardness, breaking strength and elongation at break was investigated. Obtained results were compared with ones obtained for commercial plasticizer dioctyl phthatale (DOP). Evaluation of economic potential of new technology for plasticizers production, i.e. results of techno-economic analysis, was presented. Benefits of the presented technology was based on the use of waste PET which is related to both environmental protection and profitability aspects.

Waste PET glycolyzed product and UPes were characterized by FTIR and NMR spectroscopy, elemental analysis, acid value (AV), hydroxyl value (HV) and iodine value. Nanocomposites, based on unsaturated polyester resins and hexamethyldisilazane modified silica nanoparticles, were prepared with intention to show one of valuable applicative commercialization of UPe resin. In order to determine potential of the possible implementation of developed new technology for UPe production some aspect of techno- economic analysis was analyzed. Economic potential/benefit and process profitability of the presented technology was based on the use of recycled raw input materials, i.e. waste PET, which is one of the most effective ways to save natural resources, protect the environment, and save money. Principles of green economy was incorporated in the results of developed UPe production technology which is related to both environmental protection and profitability achievement with no additional negative impact to environment, i.e. pollution decrease without negative effect of implemented technology.
