Carboxymethyl cellulose – ammonium chloride on electrical of plasticized propylene carbonate solid bio-polymer electrolytes (SBPs) using experimental and computational studies

Abstract

GRAPHICAL ABSTRACT ABSTRACT Thermal conductivity was measured using carboxyl methylcellulose (CMC) doped with ammonium chloride (AC) with varied amounts (0 – 12 wt. %) of propylene carbonate (PC) solid bio-polymer electrolytes (SBPs) via solution casting technique. In SBPs system, the frequency dependence of ionic conductivity, ϵr, and Mi were measured by using an electrical impedance spectroscopy method in the temperature range of 303 – 328 K. The highest ionic conductivity on the SBPs system is 1.01 × 10−2 S cm−1 for a sample containing 8 wt. % of PC. The system was found to obey the Arrhenius rule, where R2 ≈ 1. The dielectric studies show non-Debye behaviour for CMC-AC-PC SBPs. It is convenient to trust that the PC is one of the most promising plasticizers to enhance ionic conductivity and performance for SBP system.
