Conductivity and dielectric properties of proton conducting poly (Vinyl)chloride (PVC) based gel polymer electrolytes

Poly (vinyl) chloride (PVC)-NH4I-EC films have been prepared by the solution cast technique. The sample containing 30 wt.% NH4I exhibited the highest room temperature conductivity of 4.60 × 10-7 S cm-1. The conductivity increased to 1.08 × 10-6 Scm-1 when 15 wt.% of ethylene carbonate (EC) was added...
