PVC based nanocomposite heterogeneous cation exchange membranes constructed using solution casting procedure, in which additive compound, ZnO nanoparticle (10 wt.%), applied in membrane fabrication. An intense electrical field was applied on the prepared membranes. The impact of electrical poling voltage and duration time on resistance and microstructure of ion exchange membranes was investigated. The electrical resistance declined sharply via extraordinary voltage and time of poling. Moreover, two-phase structure model was used to study the morphological of membranes. According to two-phase model the heterogeneity of poled membranes enhanced under poling conditions. These empirical findings provide a new understanding of PVC/Nano-ZnO ion exchange membrane modifications that is comparable to other commercials.
