Dielectric properties of Ag/PAN nanocomposites

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 we...

Zusammenfassung: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.
