In the present work, solid polymer electrolyte using poly(vinyl alcohol) (PVA) and magnesium perchlorate (Mg(ClO4)2) in different compositions has been prepared by the solution-casting technique method. Surface feature of films was characterized by scanning electron microscopy (SEM) measurement. X-ray diffraction (XRD) was used to determine the complexation of the polymer with the salt. The electrophysical characteristics were measured and analyzed as dependent on the concentration, nature of the solid polymer electrolyte component and ambient temperature. A maximum ionic conductivity value of ∼10–4 S/cm at 303 K is obtained for PVA0.6/(Mg(ClO4)2)0.4 composite. The ionic transference number of Mg+2 mobile ions has been estimated by a dc polarization method. The result reveals that the conducting species are predominantly ions.

Maximum Conductivity

In this work, solid polymer electrolyte compose of blended 30% poly (methyl methacrylate) grafted natural rubber (MG30)-poly (ethyl methacrylate) (PEMA) polymer blend doped with Lithium trimethasulfonate (LiCF3SO3) films were prepared by solution casting technique. . FTIR analysis showed that the interactions between lithium ions and oxygen atoms occur at the carbonyl functional group C=O where there is shifting in wavenumber from 1728 cm-1 of pure blend to lower wavenumber of blended MG30-PEMA on the MMA structure in both MG30 and PEMA. DSC analysis showed miscibility of polymer blend. From Electrochemical Impedance Spectrocopy analysis, ionic conductivity increase with the increasing of salt concentration. Maximum conductivity at room temperature is 9.20 x 10-6 Scm-1 was obtained when 30 wt% of LiCF3SO3 was added into the system. Ionic conductivity temperature dependence plots found obeys the Arrhenius rule.
