Conductivity studies on (PVC/PEMA) solid polymer blend electrolyte films complexed with NaIO4

Abstract

PVC—PEMA polymer blend based electrolyte films complexed with NaIO4 were prepared by solution—cast technique. The complexation of the blend with the salt was confirmed from XRD and SEM studies. DC conductivity was measured in the temperature range 303–398 K. The electrical conductivity increased with increasing dopant concentration. Which is attributed to the increase in amorphous nature of the complexes on dopining.. Transference number measurements were carried out to investigate the nature of charge transport. The discharge characteristics of the cells were studied under a constant load.
