Design of plasticized proton conducting Chitosan: Dextran based biopolymer blend electrolytes for EDLC application: Structural, impedance and electrochemical studies
In this work, for the use of an electrical double-layer capacitor (EDLC) device applications, the fabrication and characterization of solid polymer electrolytes (SPEs) based on chitosandextran (CS-DN) blended polymer doped and plasticized with ammonium thiocyanate (NH4SCN) and glycerol are studied,...
