Abstract
In order to obtain new organic-inorganic hybrid materials the method e xploiting the phenomenon of polymer crazing was investigated. Polyprop ylene and polyethyleneterephtalate films were subjected to crazing to achieve high porosity. Incorporation of hydrated oxides of Mo and W in porous polymer matrix was performed by hydrolysis of alkoxides in por es using counterflow diffusion technique. It was shown that peculiarit ies of the hydrolysis of the initial compounds affect significantly th e distribution of substances inside porous polymer matrix and the poss ibility of accumulation of inorganic component inside the film. Mo mat ter in contrast to W is easily incorporated in the polymer matrix to f orm a well-defined layer. These samples demonstrated high photosensiti vity.
