Structural and Ionic Transport Study on CMC Doped NH4Br: A New Types of Biopolymer Electrolytes

A.S. Samsudin and M.I.N. Isa

Abstract:
The development of new solid Biopolymer Electrolyte (BEs) system based on Carboxy Methylcellulose (CMC) is creating opportunity for new types of electrochemical devices which may themselves, in turn, revolutionize many industrial areas. Biodegradable CMC doped with ammonium bromide (NH4Br) as BEs were prepared via solution-casting method. The polymer-salt complexes have been analyzed through FTIR spectroscopy, XRD measurement and impedance measurement. The sample containy 25 wt.% NH4Br exhibited the highest room temperature conductivity of 1.12x10-4 Scm-1. Small Polaron Hopping (SPH) model has been found to be most appropriate for fitting the experimental conductivity data.
