This paper reports on structural, morphological and electrical properties of solid polymer electrolyte films based on PVC complexed with different concentrations of VO 2+ using solution cast technique. The films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and impedance spectroscopy studies. X- ray diffraction (XRD) results revealed that the amorphous nature of PVC polymer matrix increased with the increase of VO 2+ ions concentration. The electrical conductivity was evaluated from impedance spectroscopy studies in the temperature range 303- 373 K and the conductivity was found to increase with increasing dopant concentration. The polymer complexes exhibited Arrhenius type dependence of conductivity with temperature. The variation in film morphology was examined by scanning electron microscopy (SEM).
