|Abstract:||The conductivity of proton conducting polymer electrolytes obtained by the complexation of ammonium hexafluorophosphate (NH4PF6) with polyethylene oxide (PEO) increases with the addition of propylene carbonate (PC) (plasticized polymer electrolyte) and nano size fumed silica (nano composite polymer electrolytes). Plasticized polymer electrolytes have higher conductivity whereas nanocomposite polymer electrolytes have better mechanical properties. The simultaneous addition of PC and fumed silica leads to the formation of electrolytes with higher conductivity (4.5010-5 S/cm at 25oC) as well as better mechanical strength. The curved nature of log conductivity versus reciprocal temperature plot suggests the amorphous nature of these electrolytes and a small change in conductivity observed over the 20oC to 100oC temperature range is also suitable for their use in applications.|
