Frequency dependence of the electrical conductivity in Ag/PAN nanocomposites
The frequency dispersion of the electrical conductivity of silver/polyacrylonitrile nanocomposite films is studied at various temperatures and AgNO 3 contents in an initial mixture. The frequency dependences of the nanocomposites in the range 10 3 –10 6 Hz are found to be well described by power law...
