Ionic conductivity studies of Lithium Based Polymer Electrolytes from modified Chitosan

Ionic conductivity studies of Lithium Based Polymer Electrolytes from modified Chitosan

In the present work, blending of Lauroyl Chitosan (L-chitosan) and poly (methylmethacrylate) (PMMA) was used as the polymer host and lithium triflate (LiCF3SO3) as the doping salt for the preparation of solid polymer electrolytes. Samples have been prepared by solution cast technique and were charac...
