Conductivity and Structural Studies of PEMA/ENR-50 Blend with LiCF₃SO₃ Salt

Abstract:

Solid polymer electrolytes (SPEs) comprising of a blend of Poly (ethyl methacrylate) (PEMA) and Epoxidized natural rubber-50 (ENR50) as polymer host and lithium triflate (LiCF₃SO₃) as dopant were prepared by solution cast technique. The blend based polymer electrolytes have a fixed PEMA/ENR50 ratio of 70:30 by wt. % as at this ratio ENR-50 imparted stable mechanical properties to the otherwise fragile PEMA. The incorporation of LiCF₃SO₃ into the blend is found to increase the conductivity of PEMA/ENR50. The highest conductivity achieved was 3.64 x 10^-5 Scm^-1 at 40wt. % LiCF₃SO₃. The structure of the samples was investigated by X-ray diffraction and the results show that the highest conducting sample is the most amorphous.
