Structural and Transport Properties of PVC Blend PEG Doped with Mg(ClO4)2 Solid Polymer Electrolyte

An attempt was made to investigate the effect of Mg(ClO4)(2) concentration in PVC-PEG blend polymer electrolyte system. Solid polymer electrolyte films of PVC-PEG-Mg(ClO4)(2) have been prepared by using solution casting process. Structural and transport properties have been studied by employing experimental tools like XRD, FT-IR and DC electrical conductivity. The XRD, FTIR studies were confirmed the formation of a polymer-salt complex. The conductivity results indicated that the incorporation of Mg(ClO4)(2) salt into PVC-PEG polymer; at low concentrations the increase in the conductivity is large, but at higher concentrations the increase in conductivity is modest. Using this electrolyte, an electrochemical cells have been fabricated with the configuration Mg/ (PVC-PEG-Mg(ClO4)(2)) electrolyte / (I-2 + C + electrolyte) and its discharge characteristics were determined.
