Effect of ZnO nanoparticle content on the amorphousness of conducting jackfruit seed starch-PVA blend polymer electrolyte

Abstract Nanocomposite polymer electrolyte films based on a blend of two polymers jackfruit seed starch (JSS) and poly (vinyl alcohol) (PVA) complexed with nano-particle zinc oxide (ZnO) (i.e., (50 wt% JSS/50 PVA) + x ZnO where = 0, 2, 4, 6, 8, 10, 12 14) were prepared by using the casting solution method. Electrochemical impedance spectroscopy (EIS) has been employed between frequencies 10 Hz 1 MHz to get optimum values conductivity films. The effect nano-filler concentration chemical bonding, crystallinity, morphology, ionic studied. maximum at ambient temperature 1.10 × –6 S cm −1 was obtained for JSS-PVA film it is attributed highest amorphous content.
