Abstract

Materials characterization and dielectric studies of a newly synthesized Na⁺ ion conducting nanocomposite polymer electrolytes (NCPEs): (1-x)[75PEO:25NaPO₃]+xTiO₂, where 0<x<18 wt.%. are reported. The composition: [95(75PEO:25NaPO₃)+5 TiO₂] with ionic conductivity (σ) ~ 2.3×10^-5 S.cm^-1 have been identified as optimum conducting composition (OCC). Material characterizations have been done with the help of X-ray diffraction (XRD), scanning electron micrograph (SEM), differential scanning calorimetric (DSC) and thermogravimetric (TGA) analysis. Dielectric constant(ε*) and dielectric loss (ε_l) measurements have been carried out using different experimental techniques. The conductivity enhancements in the present NCPEs have been discussed on the basis of existing theories of dielectrics.
