  • Abstract

    A series of different composition ratio of polymer electrolytes based on poly (ethylene oxide) PEO as host polymer, magnesium triflate Mg (CF3SO3)2 as salt and nanochitosan as filler was produced using hot press technique. The complexation of composite polymer electrolyte was confirmed by FTIR. The nanocomposite polymer electrolyte exhibited highest ionic conductivity in the order of 3.41x10-3.1 S/cm at 60 C and showed the dependence of the dissolved magnesium salt and nanofiller. The structural and conformational changes in the polymer host due to entrapment of nanoparticles in the filler and ion-polymer interaction were investigated by SEM method. The DSC results show the role of filler in de-linking the cross linked polymer chains and thereby increasing the ionic conductivity.
