- Аннотация: The synthesis, structure, and electrophysical properties of a polymer-inorganic biocompatiblecomposite based on unsaturated chitosan ether, namely, allyl chitosan, and vinyltriethoxysilane are studied.During composite synthesis, allyl chitosan forms an individual nanophase with vinyltriethoxysilane and itscondensation products in the polymer matrix of allyl chitosan. The size of nanoparticles embedded in a polymer matrix increases from 50 to 1000 nm as the fraction of the added vinyltriethoxysilane grows. Under exposure to UV radiation, both homopolycondensation and heteropolycondensation occur in the composite filmsvia crosslinking according to the radical mechanism and the composite becomes insoluble in water. It hasbeen shown that the resulting composites feature ionic conductivity under application of both direct currentand high-frequency electric fields to the sample. Conductivity is provided by a proton–electron ensemblethat concentrates at the nanoparticle/polymer matrix interface.
