Abstract:

Solid polymer electrolytes (SPEs) consisting of poly (vinyl chloride) complexed with MnSO4 have been synthesized by solution casting method. The ionic conductivity, dielectric response of the SPE system is studied within the frequency range 100 Hz – 2 MHz. The electrical conductivity was evaluated from ac impedance spectroscopy studies in the temperature range 303-363 K and the conductivity was found to increase with increasing temperature. The maximum ionic conductivity value 1.36 x10-4 S/cm has been observed for 5 mol% at 363 K using impedance spectroscopy technique. Dielectric relaxation studies of the polymer electrolyte have been undertaken and the results are discussed. It is observed that magnitude of dielectric permittivity is high in the lower frequency region due to electrode polarization (EP) effect.
