This is a novel approach to get polyblend films with improved properties such as ionic conductivity and dielectric strength. Different ratios of PEG (5%, 10%, 15%, 20%, 25%, 30%) are added with optimized PVA: PVP ratio. PVA: PVP: PEG based BPEs are prepared by using solution casting method. The polymer PEG act as a plasticizer and chemically stable in air.The prepared electrolytes are characterized by XRD, FTIR and ionic conductivity studies. The XRD analysis shows amorphous nature of the polyblend electrolytes. Dielectric analysis is carried out for the BPEs. The higher conductivity is obtained for 20% PEG added polyblend electrolytes and it is 9.0x10-9 S/Cm. Thus, PVA: PVP: PEG (40:40:20) system is confirmed as optimized one for further studies to enhance the ionic conductivity
