Polymer electrolyte system based on polyvinyl alcohol (PVA) complexed with NaIO4 has been prepared using solution cast technique. DC conductivity of the films were measured in the temperature range 303– 398 K. The electrical conductivity increased with increasing dopant concentration, which is attributed to the formation of charge transfer complexes. The polymer complexes exhibited Arrhenius type dependence of conductivity with temperature. The total ionic transport number was evaluated by means of Wagner's polarization technique .Transport number for Sodium ion is ranged from 0.91 to 0.96 depending on the composition. The features of complexation of the electrolytes were studied by X-ray diffraction.
