Studies Of Ionic Conductivity And A.C. Conduction Mechanism Of 2-Hydroxyethyl Cellulose Based Solid Polymer Electrolytes

Solid polymer electrolyte (SPE), which contained of 2-hydroxyethyl cellulose (2-HEC) and ammonium nitrate (NH4NO3), was prepared using solution casting method. The ionic conductivity and a.c. conduction mechanism of the SPE was analysed using electrical impedance spectroscopy (EIS). The highest ionic conductivity of (4.51±0.10) × 10-4 Scm-1 was achieved for film containing 12 wt.% of NH4NO3. The temperature dependence of exponent s was observed to be almost independent of temperature. This conduction mechanism study of 2-HEC-NH4NO3 SPE was proven to follow quantum mechanical tunneling (QMT) model.
