The aim of this paper is to prepare and study the (D.C.) electrical conductivity of (PVA-Ni(NO₃)₂) composites at different temperatures. For that purpose, PVA films with Ni(NO₃)₂ salt additive were prepared with different concentrations 2, 4, 6, 8 and 10 wt. % and with thickness of 45μm by using casting technique. The experimental results for PVA-Ni(NO₃)₂) films show that the (D.C.) electrical conductivity increased with increasing the filler content and the temperature, and the activation energy was decreased with increasing the filler content.
