Optical and Electrical Properties of Polymer Blend Electrolyte Containing Sodium Carboxyl Methylcellulose, Poly (acrylamide-co-acrylic acid), and Sodium Sulfide

Abstract

Polymer blend electrolyte thin film comprised of sodium-carboxyl methylcellulose (Na-CMC), poly (acrylamide-co-acrylic acid) (poly (AM-co-AA)), and sodium sulfide (Na2S) salt were solution cast successfully. The code of these materials represented by P-Na-S in this paper. Characterization techniques such as fourier transform infra-red (FTIR) and impedance spectroscopy were carried out to investigate complex formation and ionic conductivity of P-Na-S blend electrolyte film, respectively. The highest room temperature (RT) ionic conductivity of P-Na-S blend electrolyte film is 9.82 × 10-07 S cm-1. The temperature dependence of ionic conductivity of P-Na-S blend electrolyte film found to follow the Arrhenius rule. The activation energy (EA) obtained at 0.15 eV. The FTIR study confirmed the functional group complexation of P-Na-S in the solid polymer blend electrolyte film
