| 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 (4.50 10-5 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. |
