Abstract
Solid polymer electrolytes (SPEs) consisting of polyethylene oxide (PEO) /Polyvinyl pyrrolidone (PVP) complexed with sodium nitrate have been synthesized by solution casting technique. Structural studies were carried out using X-ray diffraction (XRD) measurements. The complex formation between the bonding of polymers and the salt were confirmed by Fourier Transform Infrared (FT-IR) spectral data. The ionic conductivity and dielectric response of the SPEs were studied within the frequency range of 42 Hz–1 MHz at the temperature range of 303–363 K. The maximum ionic conductivity was found to be 6.157 × 10−7 S/cm at 303 K for PEO (67 wt %) /PVP (27 wt %)/NaNO3 (6 wt%). The dielectric properties were also studied using the complex dielectric permittivity spectra of the SPE films. The higher dielectric permittivity was obtained due to accretion of ionic charges at lower frequencies. The surface morphology of the polymer blend electrolyte film complexed with sodium nitrate was studied using Scanning Electron Microscopy (SEM).
