Composite filmsof (polyvinyl alcohol (PVA)) doped with CuCl salt were prepared using casting technique. The CuCl salt added to polyvinyl alcohol with different weight percentages are (0, 1, 1.5 and 2) wt. %. Results showed that the absorbance increases with increase the weight percentage of CuCl. The absorption coefficient, extinction coefficient, refractive index and real and imaginary parts of dielectric constants are increasing with increase CuCl concentration. The effect of annealing on the optical properties for (PVA/CuCl) composite films with different concentrations (0, 1, 1.5 and 2) wt.% of copper chloride salt were compared and the result shows that the transmittance decreased after annealing for all the composite films. The energy gap ( ) of all the composite films decreased after annealing. The coefficient of thermal conductivity increase by increasing the concentration of the CuCl salt.
