Abstract
The changes in the specific surface area and composition of donor-acceptor sites caused by hydration and thermal treatment of dispersed BaTiO3 were determined. Modified barium titanate was mixed with cyanoethyl polyvinyl alcohol to form composite films with a relative permittivity of up to 180. The relationship between the functional composition of the surface and the particle size of modified barium titanate, on the one hand, and the relative permittivity of the composite film, on the other, was derived within the framework of the thermodynamic model. This relationship makes it possible to predict the effect of modification on the electrophysical properties of polymer composites.
