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.
