In this study, the properties of thermal and dielectric Constant and electrophoresis of polyvinyl alcohol (PVA) membranes with different concentrations (0, 3, 5, 7 and 10 wt%) of CuCl powder were investigated. A mixture was prepared using ultrasound technique for the distribution and homogeneity of the powder in the comparator polymer. The thermal conductivity (k / w / m.c) of the casting membrane was examined. The thermal conductivity of this polymeric system was increased by increasing the concentration of copper chloride. At 5% concentration, high thermal conductivity was observed, followed by a decrease in the values that followed. The electrical insulation and the electric permittivity were measured as a function of the percentage of the material. The results showed a gradual improvement in the durability of the electrical insulation by increasing the copper chloride material.
