Synthesis of Polypyrrole / Mno2 Composite and Characterization
Priti N. Jadhav | Dr. K. V. Sukhatankar
Abstract: This work is related with electrodeposition of composite form of MnO2 and polypyrrole (PPY) using Potentiostatic electrodeposition Method, and study of super capacitive behaviour. Here supercapacitive behaviour is studied by Cyclic Voltammetry technique in 1M of Na2SO4, maximum specific capacitance for composite material is 128F/gm and maximum columbic efficiency is 99.97%.Similarly supercapacitive behaviour is also studied by charging-discharging, Nyquist Impedance spectroscopy. Surface morphology is observed by scanning electron microscope (SEM), x-ray diffraction (XRD), and Raman spectroscopy technique.
