Structural and Electrical Properties of Plasticized Radiation Induced Chitosan Grafted Poly(methylmethacrylate) Polymer Electrolytes

Plasticized grafted polymer electrolytes composed of chitosan-grafted-poly(methylmethacrylate) (Ch- g-PMMA), ethylene carbonate (EC) plasticizer and lithium triflate (LiTf) salt were prepared by the solution cast technique. Impedance spectroscopy was performed in the temperature range of 303-373 K....

Description
Summary:Plasticized grafted polymer electrolytes composed of chitosan-grafted-poly(methylmethacrylate) (Ch- g-PMMA), ethylene carbonate (EC) plasticizer and lithium triflate (LiTf) salt were prepared by the solution cast technique. Impedance spectroscopy was performed in the temperature range of 303-373 K. The highest conductivity of 1.63 x 10-4 Scm-1 was obtained for the salted grafted polymer with 50 wt% and enhanced to 2.23 x 10-4 Scm-1 with the addition of 30 wt.% EC. The temperature dependence conductivity data obeys Arrhenius relationship. Dielectric behavior was analyzed using complex permittivity (s) and electrical modulus formalism (M) for the highest conducting unplasticized and plasticized samples at various temperatures. The structure and complexation of the electrolyte were studied by Fourier transform infrared (FTIR) spectroscopy.
