Abstract

Electrical noise associated with ion transport (termed as "ionic noise") has been measured at different temperatures, using a lock-in amplifier and dynamic signal analyzer for a polymer electrolyte PEO:NH4I and its US dispersed composite. The ionic noise suddenly increases as the polymer passes through its phase transition at T-g and T-m. The T-g-peak in the noise measurement appears more clearly than what it does in DTA/DSC or conductivity measurements. Therefore, we suggest the noise technique as a good probe for studying phase transitions in ion conducting solid electrolytes. Further, the present noise measurements also confirm the known results of DTA/DSC studies that both T-g and T-m of polymer electrolytes shift on the formation of composites.
