In this research, thin, transparent and flexible free standing films of poly(methyl methacrylate) (PMMA) / deproteinized natural rubber (DPNR) / lithium triflate (LiCF3SO3) were obtained by solvent casting method at all DPNR compositions. The highest ionic conductivity obtained was 1.46 x 10-9 Scm-1 at room temperature when 20% of DPNR were blended into the system. As the concentration of DPNR increased, the conductivity drops drastically due to the insolubility of lithium salt in higher concentration of DPNR. From the FTIR analysis it was confirmed the formation of polymer-salt interaction in the electrolyte system.
