摘要：

Poly(vinyl) chloride (PVC)-NH4I-EC films have been prepared by solution cast technique. The sample containing 30 wt. % NH4I exhibited highest room temperature conductivity of 4.60 x 10(-7) S cm(-1). The conductivity increased to 1.08 x 10(-6) Scm(-1) when 15 wt. % of ethylene carbonate (EC) was added to 70 wt. % PVC - 30 wt. % NH4I. Fourier Transform Infrared (FTIR) showed evidence of polymer salt complexation while DSC showed increase in glass transition temperature (T-g) of PVC -NH4I - EC polymer electrolytes. The conductivity behavior of the studied system could be accounted by the changes in T-g values.
