摘要：

The solid polymer electrolyte films composed of polyvinyl alcohol (PVA) with various concentrations of sodium nitrate (NaNO3) salt have been prepared by solution casting technique. The bond structure and amorphous nature has been confirmed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis respectively. The AC conductivity values have been measured in the frequency range 42 Hz-100 KHz for the films (PVA:NaNO3 = 90:10; 80:20; 70:30; 60:40). The polymer electrolyte with composition 30 wt% of NaNO3 shows the highest conductivity of 2.33x10(-6) S/cm. Activation energy is found to be 0.19 eV.
