Abstract
A conducting polymer electrolyte based on carboxy methylcellulose (CMC) complexed with different concentrations of salicylic acid (SA) has been investigated. The ionic conductivity of the solid polymer electrolyte (SPE) of pure CMC obtained at room temperature is 8.49 × 10− 10 S cm− 1. The maximum ionic conductivity achieved in the solution-cast films at room temperature is 9.50 × 10− 8 S cm− 1for CMC incorporated with 7 wt. % SA. In addition, the temperature dependence of the SPE system exhibits Arrhenius behavior. Dielectric data were analyzed using complex permittivity ε* and complex electrical modulus M* for the sample with the highest ionic conductivity at various temperatures and found is non Debye behavior.
