The Effect of LiCF₃SO₃ Complexed MG30-PEMA Blend Solid Polymer Electrolyte

Abstract:

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.
