Gorbyk Chuiko Institute of Surface Chemistry, NAS of Ukraine, Kiev, 164 03164, UA Journal Article 2014 07 30 Abstract Polymer composite materials based on CuS/CdS, Cu 2 S/CdS and Ag 2 S/CdS were obtained by substitution of Cd with Ag, Cu (II) and Cu (I) ions in the CdS rod-like nanocrystalline and investigated their electrophysical properties. It was found that the electrical conductivity of CuS/CdS heterostructure is in five orders higher compared to the CdS. It was shown that the values of the complex permittivity at identical content of CuS and Cu 2 S nanoparticles are more than 40 % higher for the 0.3 Cu 2 S/CdS-PVDF system in comparison with the 0.3 CuS/CdS-PVDF.
