摘要：
The temperature dependences of the dielectric permittivity and conductivity of nanocomposites on the basis of nanoparticles of copper sulfide and a polymer matrix (polyvinyl alcohol) were investigated in the frequency range of 265 Hz-1 MHz. The activation energies of the charge carriers were determined using the temperature dependence of the conductivity. It was found that this energy depends on the size of the formed particles. The alteration of the conductivity values dependent on the number of cycles is associated with the redistribution of nanoparticles over the cross section of the polymer matrix.
