Abstract

The electrical conductivity and thermal conductivity of carboxyl methylcellulose doped with oleic acid and plasticized with glycerol have been measured by the electrical impedance spectroscopy method in the temperature range of 303 – 393 K. The composition of glycerol was varied between 0 and 50 wt. % and the samples were prepared via solution casting technique. The highest ionic conductivity at room temperature, σrt (303K) is 1.64 x 10-4 S cm-1 for sample containing 40 wt. % of glycerol. The system was found to obey Arrhenius rule where R2 ≈ 1. The dielectric study (,) shows a non-Debye behavior.

 

Key words: Solid polymer electrolyte, carboxyl methylcellulose, oleic acid, glycerol.
