|Abstract:||Solid polymer electrolyte based on poly (vinyl pyrrolidone) (PVP) complexed with different weight per cent ratios of KClO4 salt was prepared using solution cast technique. The complexation of the salt with polymer was confirmed by Fourier transform infrared (FT-IR) spectroscopy studies. Electrical conductivity was measured with ac impedance analyzer in the frequency and temperature range 1 Hz-1 MHz and 303 K-373 K, respectively. It was observed that the magnitude of conductivity has increased with the increase in the salt concentration as well as the temperature. The variation of ac conductivity with frequency obeys Jonscher power law. The dynamical aspects of electrical transport process in the polymer electrolyte were analyzed using complex electric modulus. The modulus spectra reveal the non-Debye nature of the material.|
