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.en-USSolid polymer electrolytes, 2-hydroxyethyl cellulose, ammonium nitrate, ionic conductivity, quantum mechanical tunnelingArticle6570Special Issue Number 2: Fundamental Interdisciplinary Pathways To Future Sustainability
