Abstract: The dependence of electric modulus on the frequency of an ac electric field is studied for the silver/polyacrylonitrile nanocomposite films at several measurement temperatures and AgNO$_3$ contents in the original mixture. It is demonstrated that the frequency dispersion of dielectric properties is well described with the aid of the Cole–Davidson model. The relaxation maxima on the curve of the imaginary part of the electric modulus versus frequency are interpreted using the interfacial polarization.
