Abstract: Poly vinyl alcohol(PVA) and Poly ethylene glycol (PEG) blend based polymer electrolytes has been prepared using Mg(CH3COO)2 and Mg(NO3)2 as salt by varying the PEG: [Mg(CH3COO)2 and Mg(NO3)2] ratio. The ionic conductivity of the prepared films was studied through XRD and AC impedance techniques. The temperature dependence conductivity shows Arrhenius behavior. The maximum conductivity of 9.852X10-6 S/cm was observed for the film with composition PVA-PEG- [Mg(CH3COO)2 +Mg(NO3)2]: (40-45-7.5-7.5)
