Abstract: Poly[bis(methyoxy-ethoxy-ethoxy)phosphazene] (MEEP) has been prepared from hexachlorocyclotriphosphazene by polymerizing the latter and then replacing the Cl groups by methoxy ethoxy-ethoxy groups to obtain a completely amorphous polymer. Mixed electrolyte of MEEP, PEO and NaSCN have been prepared by varying NaSCN concentration in the electrolyte while maintaining the ratio of MEEP and PEO constant at 55:45. The mixed electrolytes showed the highest electrical conductivity of 5 x 10(-5) S cm(-1) at room temperature which is two orders of magnitude higher than PEG-based systems. Mixed electrolytes have been characterized by infrared and differential scanning calorimetry. The transport numbers of Na+ and SCN- are 0.92 and 0.08 respectively. Addition of PEG, to amorphous MEEP introduces crystalline PEO-NaSCN phases into the mixed electrolyte system.
