Ionic Conduction Behavior of CMC Based Green Polymer Electrolytes
Abstract:
The present work deals with the findings on the ionic conduction behavior based on ethylene carbonate (EC) as plasticizer in carboxymethyl cellulose (CMC) – dodecyltrimethyl ammonium bromide (DTAB) for green polymer electrolytes (GPEs) that were prepared via solution casting technique. The highest ionic conductivity obtained for CMC-DTAB film was 7.72 x 10-4 S/cm and enhanced to 2.37 x 10-3 S/cm with addition 10wt. % of EC. The conductivity-temperature of GPEs system obeys the Arrhenius relation where the ionic conductivity increases with temperature. The temperature dependence of the power law exponent for plasticized CMC-DTAB based GPEs system follows the quantum mechanical tunneling (QMT) model for conduction mechanism.
