Abstract

Investigations on Sodium-ion conducting polymer blend electrolyte sys- tems based on PEO/ PVP, complexed with NaIO4 salt and TiO2 nanollers were presented in this report. The complexed polymer blend electrolytes were prepared in the form of dimensionally stable and free-standing lms by conventional solution cast technique. Micro Raman and XRD studies con- rmed the miscibility between PEO and PVP and the complexation of the salt with PEO/PVP polymer host. TEM measurements were carried out to evaluate size & distribution of the dispersed TiO2 nanollers. Complex impedance spectroscopy in the frequency 1 Hz { 1 MHz within the temper- ature range from room temperature to 343 K. Ionic conductivity of blend electrolytes increased with the increase of TiO2 nanollers concentration. Electrical conductivity and dielectric properties of NaIO4 salt complexed blend PEO/ PVP/Na+ electrolytes were analysed as a function of TiO2 nanollers concentration
