Conductivity and dielectric behavior studies on solid polymer electrolyte based poly(methyl methacrylate) (PMMA) grafted natural rubber (MG49) polymer blends

A series of solid polymer electrolyte films, employing 49% poly(methyl methacrylate)(PMMA)-grafted natural rubber (MG49) as polymer host and lithium tertrafluoroborate (LiBF4 ) as conducting material were prepared by solution casting technique. The films of MG49-LiBF4 , MG49-PMMA and MG49-Poly...
