Effect of PC on Solid Polymer Electrolyte Based on PVA

S. Kavitha, S. Karthieswari, Dr K. P. Radha

Abstract :

Solid polymer electrolytes based on Poly(vinyl alcohol) (PVA) as host polymer, ammonium chloride (NH4Cl) as salt and propylene carbonate (PC) as plasticizer have been prepared by solution casting technique. The prepared polymer electrolytes have been characterized by impedance spectroscopy and FTIR spectroscopy. The FTIR analysis reveals complex formation among the polymer, salt and plasticizer of the electrolytes. From ac impedance spectroscopic studies, it has been found that 85PVA:15NH4Cl:20 PC has high ionic conductivity of 2.16×10-5 Scm-1 at ambient temperature. The temperature dependent conductivity of the electrolyte obeys the Arrhenius equation. The activation energy of the high conductivity sample 85 PVA:15 NH4Cl: 20 PC is 0.138 eV, which is considerably lower than that of the electrolyte without the plasticizer.
