Description
Summary:The dependence of the electric modulus of silver/polyacrylonitrile nanocomposites on the ac field frequency has been studied at different temperatures and AgNO 3 content in the base mixture. The observed relaxational maxima on the frequency dependences of the electric modulus’ imaginary part are connected with the interfacial polarization. It was shown that the frequency electric modulus’ experimental points are well-described by the Cole-Davidson model, correspondingly. The values of the relaxation times and the activation energies of these structures have been estimated by this model.
