Effect of Adipic acid on PVA based proton conducting polymer electrolyte
The proton conducting solid polymer electrolytes composed of Poly vinyl Alcohol (PVA) with different concentration of adipic acid (C6H10O4) have been developed by using solution casting technique. The prepared polymer electrolytes have been subjected to XRD, DSC, AC impedance and Wanger’s dc Polarization studies. XRD analysis confirms amorphous nature of polymer electrolytes. DSC analysis reveals that the best ion conducting sample 75 PVA: 25 C6H10O4 polymer electrolyte has more thermal stability than pure PVA polymer electrolyte.The highest ionic conductivity has been found to be 7.5010-5 Scm-1 at 303 K for 75 PVA: 25 C6H10O4 polymer electrolyte. Temperature dependent conductivity of polymer electrolytes obeys Arrhenius equation. The highest conductivity polymer electrolyte 75 PVA: 25 C6H10O4 has low Activation energy 0.2744eV among the prepared polymer electrolytes. The transference number of electrolyte in the highest ion conductivity sample is 0.95. Wanger’s dc Polarization analysis suggests that the prepared polymer electrolytes are the best proton ion conductors.
