AB  - This study presents an analysis of films which consist of two layers; one layer is PVDF as the matrix, along with fillers BaTiO3 (BT), and the second is one bacterial nanocellulose (BNC) filled with Fe3O4. The mass fraction of BT in PVDF was 5%, and the samples were differentiated based on the duration of the mechanical activation of BT. This innovative PVDF laminate polymer with environmentally friendly fillers aligns with the concept of circular usage, resulting in a reduction in plastic content and potential improvement of the piezoelectric properties of the entire composite. This work presents new, multifunctional “green” packaging materials that potentially could be a good alternative to specific popular materials used for this purpose. The synthesis of the films was carried out using the hot press method. Tensile tests, water vapor permeability examination, and structural analyses using SEM-EDS and FTIR have been conducted. The sample PVDF/BT20/BNC/Fe3O4 exhibited the best barrier properties (impermeability to water vapor), while the highest tensile strength and toughness were exhibited by the PVDF/BT5/BNC/Fe3O4 sample.

AB  - In the search for environmentally friendly materials with a wide range of properties, polymer composites have emerged as a promising alternative due to their multifunctional properties. This study focuses on the synthesis of composite materials consisting of four components: bacterial nanocellulose (BNC) modified with magnetic Fe3O4, and a mixture of BaTiO3 (BT) and polyvinylidene fluoride (PVDF). The BT powder was mechanically activated prior to mixing with PVDF. The influence of BT mechanical activation and BNC with magnetic particles on the PVDF matrix was investigated. The obtained composite films’ structural characteristics, morphology, and dielectric properties are presented. This research provides insights into the relationship between mechanical activation of the filler and structural and dielectric properties in the PVDF/BT/BNC/Fe3O4 system, creating the way for the development of materials with a wide range of diverse properties that support the concept of green technologies.

AB  - Efficient cathodes for the hydrogen evolution reaction (HER) in acidic water electrolysis rely on the use of expensive platinum group metals (PGMs). However, to achieve economically viable operation, both the content of PGMs must be reduced and their intrinsically strong H adsorption mitigated. Herein, we show that the surface effects of hydrogenated TiO2 nanotube (TNT) arrays can make osmium, a so far less-explored PGM, a highly active HER electrocatalyst. These defect-rich TiO2 nanostructures provide an interactive scaffold for the galvanic deposition of Os particles with modulated adsorption properties. Through systematic investigations, we identify the synthesis conditions (OsCl3 concentration/temperature/reaction time) that yield a progressive improvement in Os deposition rate and mass loading, thereby decreasing the HER overpotential. At the same time, the Os particles deposited by this procedure remain mainly sub-nanometric and entirely cover the inner tube walls. An optimally balanced Os@TNT composite prepared at 3 mM/55 °C/30 min exhibits a record low overpotential (η) of 61 mV at a current density of 100 mA cm-2, a high mass activity of 20.8 A mgOs-1 at 80 mV, and a stable performance in an acidic medium. Density functional theory calculations indicate the existence of strong interactions between the hydrogenated TiO2 surface and small Os clusters, which may weaken the Os-H* binding strength and thus boost the intrinsic HER activity of Os centers. The results presented in this study offer new directions for the fabrication of cost-effective PGM-based catalysts and a better understanding of the synergistic electronic interactions at the PGM|TiO2 interface.

AB  - The effect of the weight fraction of NaA zeolite on thermal properties (specific heat capacity, thermal diffusivity, thermal conductivity) and dielectric properties (electrical conductivity, real and imaginary electric permittivity) of composites based on low-density polyethylene (LDPE) and NaA zeolite is examined. Composite samples containing from 5 to 30 wt% zeolite are prepared using the compression molding technique. The degree of dispersion and the weight fraction of filler in the LDPE/NaA zeolite composites are determined using X-ray diffraction. A linear decrease in the values of the specific heat capacity with an increase in the weight fraction of zeolite is observed using differential scanning calorimetry. The laser flash method is used to determine the thermal diffusivity of the composites. An increase in effective thermal diffusivity and abrupt increase in the range from 15 to 20 wt% of zeolite are established. It is demonstrated that effective thermal conductivity increases with an increase in the weight fraction of zeolite, and an abrupt increase in the range from 15 to 20 wt% is observed. Dielectric spectroscopy measurements are performed to determine the real and imaginary parts of permittivity. An increase of real and imaginary parts of permittivity of LDPE/NaA zeolite composites, with increasing weight fraction of zeolite, is established. Two relaxation peaks of the imaginary parts of permittivity of LDPE/NaA zeolite composites are detected. An increase of electrical conductivity with increasing weight fraction of zeolite and abrupt increase in the range 15 to 20 wt% are noticed. (c) 2021 Society of Industrial Chemistry.

AB  - The electro-physical properties of raw, alkali and oxidatively modified jute fabrics were investigated as complex phenomena of the interactions between the fabrics’ chemical composition, carboxyl group content, crystallinity, structural characteristics, moisture sorption, and frequency of the electric field. At 80% relative air humidity, chemically modified jute fabrics have 38–179% and 1.7–5.4 times higher dielectric loss tangent and effective relative dielectric permeability compared to unmodified. To further improve these properties, fabrics were treated with CuSO4 and Cu-based nanoparticles were in situ synthesized on their surfaces by reduction. A few smaller agglomerates of Cu-based nanoparticles were observed across the alkali modified fabric's surface, while smaller irregularly shaped and larger agglomerates were distributed over the oxidatively modified fabric's surface. Regardless of the type of synthesized nanostructures (metallic Cu, copper oxide (Cu2O or CuO) or their mixtures), excellent fabrics’ effective relative dielectric permeability is guaranteed. Precisely, exploitation in specific conditions that contribute to copper reduction will make jute fabrics able to store 21–163 times more energy from an external electric field than before the exploitation, which will extend their lifetime. On the other hand, with increasing the total content of Cu after the reduction and formation of agglomerates of Cu-based nanoparticles, the movements of cellulose, hemicelluloses, and lignin molecules become difficult resulting in lower energy dissipation within the chemically modified than within unmodified fabric. Applied chemical modification and coating with Cu-based nanoparticles enables designing fabrics with predictable electro-physical properties, which is very important from the application point of view.

AB  - In this investigation, the electro-physical properties (DC volume electrical resistivity, and AC-specific electrical conductivity) of woven fabrics (cotton, cotton/polyester, and flax in plain weave and cotton in satin weave), before and after abrasion on Martindale device (under a pressure of 9 and/or 12 kPa) were examined. The obtained results revealed that the cotton fabric in satin weave has the lowest resistivity and the highest conductivity. In contrast, the lowest conductivity and the highest resistivity before abrasion were observed for cotton/polyester fabric due to its lowest moisture content. Furthermore, a decrease in the conductivity and increase in the resistivity of cotton/polyester and flax fabrics in plain weave, and cotton fabric in satin weave, as well as an increase in the conductivity and decrease in resistivity of cotton fabric in plain weave were registered after abrasion at 9 kPa. After abrasion at 12 kPa cotton and cotton/polyester blend fabrics in plain weave have higher resistivity and lower conductivity than before abrasion and after abrasion at a pressure of 9 kPa. Abrasion leads to a deterioration of the fabrics' electro-physical properties and thus their comfort, especially in the case of cotton/polyester blend fabric when the pressure of 12 kPa was applied.

AB  - This work aimed to obtain jute fabrics suitable for the production of inexpensive technical textiles by using simple alkali treatments. The influences of alkali concentration (1–17.5 % NaOH) and treatment duration (5–30 min) on the fabrics’ compression properties, abrasion resistance, and sound absorption coefficient were studied in detail. With increasing the treatment severity, the fabric compressibility decreases by 19.6–33.9 % due to increased fabric compactness. In parallel, the fiber crystallinity index and hemicellulose content decrease, while the fibers’ interfibrillar regions become less dense and less rigid contributing to 19.0–27.0 % better recoverability after compression. The mercerized fabrics possessed a notably lower mass loss (4.1–5.9 %) after 750 abrasion cycles compared to the other investigated fabrics (18.9–30.9 %), which could be ascribed to the higher friction forces existing between the yarns within the mercerized fabrics and between the fibers within the yarns, as well as higher elongation at maximum force. In the case of the fabrics treated for 5 or 15 min with different NaOH concentrations, their mass losses during abrasion decrease with increasing the elementary fiber liberation, while the sound absorption coefficients increase with increasing the fabric compactness. Mercerized fabrics are capable of absorbing about 28 % to 2.7 times (at 990 Hz) and 2.0 to 2.4 times (at 4090 Hz) higher mechanical sound energy compared to the untreated fabric. The jute fabric mercerized during 30 min could be used for the production of carpet backings, while those mercerized during 5 min is the most suitable for the production of sound-absorbing materials.

AB  - This work aimed to investigate the quality of three plain single jersey weft-knitted fabrics produced from the same flax yarn but with different structural characteristics. The quality of knitted fabrics was evaluated in terms of their electro-physical and compression properties. DC volume electrical resistivity and dielectric properties (effective relative dielectric permeability and AC specific electrical conductivity) were examined in the scope of this investigation. Compressibility and compressive resilience were selected to determine the influence of compression properties on the quality of the knitted fabrics. The current study showed that the sample with the highest stitch density, weight, thickness, moisture content, and the lowest porosity, has the lowest DC volume electrical resistivity and compressibility, but the highest effective relative dielectric permeability, AC specific electrical conductivity, and compressive resilience. Based on the application of the ranking method, the best quality sfowed the knitted fabric with the most compact structure and the highest moisture content; the worst quality was manifested by the knitted fabric with the least compact structure and the lowest moisture content.
AB  - Cilj ovog rada je bio da se ispita kvalitet tri desno-leve potkine pletenine izrađene od istog lanenog prediva, ali različitih strukturnih karakteristika. Kvalitet pletenina je ocenjivan u pogledu njihovih elektrofizičkih i kompresionih svojstava. U okviru ovog istraživanja ispitivana su specifična zapreminska električna otpornost i dielektrična svojstva (efektivna relativna dielektrična propustljivost i specifična električna provodljivost). Kompresibilnost i elastični oporavak su odabrani da bi se utvrdio uticaj kompresionih svojstava na kvalitet pletenina. Sprovedeno ispitivanje je pokazalo da uzorak sa najvećom gustinom petlji, površinskom masom, debljinom, sadržajem vlage i najmanjom poroznošću ima najmanju specifičnu zapreminsku električnu otpornost i kompresibilnost, ali najveću efektivnu relativnu dielektričnu propustljivost, specifičnu električnu provodljivost i elastični oporavak. Na osnovu metode rangiranja ustanovljeno je da najbolji kvalitet ima pletenina najkompaktnije strukture sa najvećim sadržajem vlage; najlošiji kvalitet ispoljava pletenina najmanje kompaktne strukture sa najmanjim sadržajem vlage.

AB  - In the present research, folding of yarns was applied as a method for designing thermal transport characteristics of hemp-based knits. The rib-knitted fabrics were made by combining one of two cotton two-folded yarns (differing in folding twist) with one of the two complex hemp yarns. The parameters describing the thermal properties in the steady-state and transient regimes of heat transfer were determined. The results indicated that the packing density of the fibers in the yarn plays a crucial role in the heat conduction through the fabric. The two-assembled hemp component appeared to be the main heat conductor in the knitted fabrics containing it. Between the knits composed of the two-folded hemp and two-folded cotton yarns, that having two-folded more twisted cotton yarn as a component was characterized by higher thermal conductivity. The higher thermal conductivity resulted in higher thermal absorptivity, but not necessarily in higher thermal diffusivity, as the increased volumetric heat capacity may limit the speed of heat spreading through the fabric. Therefore, the knits containing two-assembled hemp yarn differed in thermal diffusivity despite their similar thermal conductivity. Both knits with the two-folded more twisted cotton yarn as a component had similar thermal diffusivity despite their different thermal conductivity.

AB  - In this work, the volume electrical resistivity and dielectric loss tangent of viscose/polypropylene multipurpose nonwoven fabrics were examined. According to the obtained results, the changes in the volume electrical resistivity depend on the applied chemical bonding agent, viscose fiber content, moisture content, fabric thickness, fabric weight, and relative air humidity. Based on the volume electrical resistivity hysteresis, the portion of sorbed moisture retained in the material after desorption, as well as the portion of moisture removed from the material during desorption, were determined. Furthermore, the dielectric loss tangent measured at the frequency range between 30 Hz and 140 kHz, for the samples exposed to different relative air humidity (40 % and 80 %) and wet samples, is dependent on the chemical bonding agent, viscose fiber content, moisture content, as well as frequency of the external electric field. The dielectric loss tangent measured at 80 % relative air humidity showed a peak at about 100 Hz, while for the wet samples, the peak was observed in the frequency range between 30 and 140 kHz. In a wet state, the dielectric loss tangent is primarily influenced by the water molecules present in the sample.
