Conductivity in blend polymer and sodium salt electrolyte system

Solid polymer Blend Electrolyte System based on Na-salt has been investigated. In the present work we have incorporated sodium triflate (according to weight percentage) in synthesized PEO/PAM polymer blend system. FTIR, DSC and SEM studies have been carried out to understand polymer blend interactions, crystalline properties and surface morphology. Electrical properties have been measured as a function of temperature and frequency by Impedance Spectroscopy. Conductivity of sample with 7.5 wt % salt concentration showed highest room temperature value of 9.907 × 10⁻⁸ S/cm. Salt concentrations >7.5 wt % showed decrease in conductivity. Increase in conductivity values upto 7.5 wt % salt is attributed to dissociation of salt and increase in amorphosity of the system.
