The temperature dependence of dielectric permeability and conductivity of nanocomposites on the basis nanoparticles of copper sulfide and polymer matrix (polyvinyl alcohol) in the range of frequency 265 Hz – 1 MHz has been investigated. From the temperature depends of conductivity charge carriers activation energy has been identified. It has been established that the activation energy of charge carriers depends on the size of formed particle. The alteration of conductivity values from numbers of cycles is connected with repartition nanoparticles in the cross-section of polymer matrix.
