Oxide systems of titanium dioxide and silicon dioxide containing platinum and palladium nanoparticles were synthesis. As a reducing agent and nanoparticles stabilizer were used heteropolyethers, obtained by controlled hydrolysis of titanium and silicon alkoxides in the presence of 1,10-decanediol.
New complex of Pd (II) with phenylacetonitrile, suitable for use as a precursor of palladium nanoparticles in the composition of metal-based composite UHMWPE was obtained. The thermodynamic characteristics of metal-polymer composite, found the effect of nanoparticles of palladium in the crystallization processes in UHMWPE and other characteristics of the material.
Represented work was done to identify possible reaction ways of titanium carboxamide complexes with various organic compounds, mainly alcohols, resulting in the formation of particles of titanium dioxide in non-aqueous media. The titanium tetrachloride and N-methylformanilide complex was selected as the subject of research. We studied the reaction of this compound with various alcohols.
A method of producing composite materials based on ultra high molecular weight polyethylene (UHMWPE) and metal oxides, such as rare-earth elements oxides (REE oxides), including gadolinium, dysprosium and tungsten oxides, was developed in this study. The surface of oxide fillers was modified using organosilicon coupling dressing agents in the acid catalysis environment. The modification allows to produce compositions containing significant amount of filler (over 30%). The effect of introduction of rare earth oxides into the matrix of ultrahigh molecular polymer up to 40% by weight on thermal and oxidative degradation was studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
