This study is an investigation of the effect of filler content and temperature on electrical properties of poly vinyl alcohol. The present work is focused on the modification of the properties of poly vinyl alcohol (PVA) with CuCl₂.2H₂O. The D.C electrical conductivity of composite has been investigated with different percentages and different thickness at different temperature. The experimental results showed that the D.C electrical conductivity increased with increasing the CuCl₂.2H₂O concentrations and temperature. Also the activation energy increased with increasing of concentration of additional salt.
