Abstract

Effect of Blending on Electrical and Electro-Chemical Studies of Solid Proton Conducting Polymer Electrolytes Based on PVP And Pmma

Author(s): C. Ambika and G. Hiran Kumar

Solid proton conducting polymer electrolytes of PVPK30 (poly vinyl pyrrolidone) –MSA (Methanesulfonic acid), PMMA (poly methyl methacrylate)-MSA and PMMA-PVPK30-MSA in various compositions are prepared by conventional solution casting technique. The conductivity values for all the prepared polymer electrolytes are calculated from cole-cole plot. The conductivity value is enhanced due to blending. The maximum conducting sample is identified in each set of polymer matrices and it is utilized for the construction of proton battery as solid electrolyte. The configuration of the primary proton battery is Zn + ZnSO4.7H2O + AC| solid polymer electrolytes |MnO2 + AC. Discharge profile of the proton battery is monitored at a constant current of 0.01 mA. Electrochemical impedance value of the constructed proton battery is calculated for both before and after discharge. Electrochemical impedance value is found decreased for the proton battery constructed with blend solid polymer electrolyte. The proton battery constructed with PMMA-MSA matrices shows poor discharge performance because of the high electrochemical impedance value.
