Abstract
It has been studied the temperature dependence of the resistivity of LDPE - CdS nanocomposites obtained by the crazing method of the polymer matrix in liquid medium and heat-treated in two different modes. It is shown that the observed cavity in temperature dependence of the resistivity in the samples, treated at T = 383K disappears in the samples treated at T = 413K. 413K is premelting temperature of polymer matrix and sample structuring and disappearance of the surface porosity occurs in nanocomposites treated at this temperature due to penetration of the main part of CdS nanoparticles in the matrix volume. Changes in electrical properties of the composite after heat treatment as shows RTL spectra occurs in the result of changes in the structure of the polymer and the nature of polymer – nanoparticle interaction.
