Synthesis and characterization of polmer gel electrolyte

Abstract

Polymer gel electrolytes were prepared by the gelation method having different O/Na ratio (O/Na = 20, 40, 60, 80, 100) taking PVdF as polymer host, sodium iodide as salt and DMF as solvent. After synthesis it is characterized with different experimental techniques. The structural and morphological characterization was done by x-ray diffraction and scanning electron microscope analysis. Similarly electrical property was studied by impedance spectroscopy. From XRD we found about crystallinity and amorphous nature of polymer gel electrolyte and from impedance spectroscopy we measured bulk resistance, dc conductivity, and other related dielectric parameters.
