A comprehensive investigation on electrical characterization and ionic transport properties of cellulose derivative from kenaf fibre-based biopolymer electrolytes
The invention of a new biopolymer electrolyte based on carboxymethyl cellulose from Hibiscus cannabinus or kenaf fibre has been accomplished by doping ammonium acetate to the polymer–salt system by a solution cast technique. The optical micrograph of all films indicated that the addition of ionic sa...
