Electrical and thermal analysis on Na+ - ion conducting novel blended solid polymer electrolyte membranes

In this study, the hot press method has been used to synthesize a blended solid polymer electrolyte (BSPE), containing poly (ethylene oxide) and polyacrylonitrile (PEO/PAN) matrix complexed with sodium perchlorate (NaClO4) salt. The film with varying salt concentration has been prepared, in which the BSPE OCC (optimum conducting composition) film exhibits the highest ionic conductivity is (σrt) ∼ 2.10 × 10-6 Scm−1 at room temperature. X-ray diffraction (XRD), Impedance Spectroscopy (IS), Differential Scanning Calorimetry (DSC) and Thermal Gravimetric Analysis (TGA) techniques have been adopted for the characterization. These investigations are demonstrated their utility and potential for all-solid-state device applications.
