Summary: This article prepared advanced biodegradable thermoplastic elastomer (BTPE)/reduced graphene oxide (rGO) nanocomposites using aliphatic diols, aliphatic dibasic acids, and graphene oxide (GO) as raw materials. The rGO is well dispersed in the BTPE matrix through its predispersion in aliphatic diols before the polycondensation of the polyester prepolymers. The addition of GO greatly enhances the tensile strength, elongation at break, biodegradability, and electrical conductivity of the BTPE/rGO nanocomposites.

Summary: Comprehensive studies using quantum chemical calculations and IR spectroscopy have shown that the interaction between ornidazole and hydroxylated and functionalized silicas is due to the formation of hydrogen bonds. The highest adsorption energy was observed for hydroxylated silica, followed by aminosilica and silica with methyl groups on the surface. Furthermore, nanocomposites based on hydroxylated, aminated, and partially methylated matrices exhibited the highest degree of release of ornidazole, while nanocomposites based on fully methylated matrices showed a decrease in the release degree.

Summary: The effect of adding small amounts of auxiliary gases to PANI nanocomposite films during plasma polymerization at atmospheric pressure was investigated. The addition of argon or nitrogen significantly improves the uniformity and regularity of the films, while adding oxygen weakens these properties. PANI films synthesized with a small amount of nitrogen show the best electrical resistance and resistance changing behavior after external I-2 doping compared to other gases.

Summary: This research investigates the effects of nano-reinforcement materials on the mechanical properties of rubber samples. The study finds that precipitated silica can improve the properties of rubber, while a combination of graphene nanoplatelets and carbon black can effectively enhance the tensile strength and elongation at break of rubber. However, the addition of graphene nanoplatelets negatively affects the abrasion resistance of the samples.

Summary: The aim of this study was to investigate the stability and morphology of polystyrene latex with kaolinite as a filler during the synthesis of nanocomposites through emulsion polymerization. Nanocomposites with different weight percentages of kaolinite (1%, 3%, and 5%) were prepared. Latexes with 1% to 3% kaolinite showed stability during the polymerization reaction, and the hydrodynamic diameters were measured to be 93.68 nm and 82.11 nm for the latexes with 1% and 3% kaolinite, respectively. XRD, SEM, and HRTEM analysis confirmed the presence of exfoliated and intercalated structures of kaolinite.
