Novel Proton Conducting Solid Bio-polymer Electrolytes Based on Carboxymethyl Cellulose Doped with Oleic Acid and Plasticized with Glycerol

Abstract

Recently, biodegradable materials attract enormous attention worldwide as a result of white pollution, one of the environmental crises. Several renewable resource-based biopolymers are suitable to be used as host polymer in the polymer electrolytes1–3, such as starch4, cellulose5–8, chitosan9–12, carrageenan13,14 and agarose15,16. The polymers can solvate the dopant if there is direct interaction between the lone pair electron of the heteroatom such as oxygen or nitrogen in the polymer and cation of the ionic dopant2,17. Therefore, it is a significant develop solid biopolymer electrolytes (SBE) by using natural polymer.
