Supercapacity of Carboxyl Graphene-Based Electroconductive Polypyrrole Composite
Abstract:
Carboxyl graphene-based polypyrrole(CG/ppy) modified electrode was prepared and its electrochemical properties were investigated via cyclic voltammetry and AC impedance.Additionally,galvanostatic charge-discharge tests and cycle stability tests were performed.Experimental results show that the CG/ppy significantly improves the current response of the bare electrode and reduces the resistance of the bare electrode in the supporting electrolyte.The specific capacitance of the CG/ppy modified electrode is up to 584 F/g and retains 81% of the initial value after 1000 cycles.Therefore CG/ppy modified electrode has potential application value in the field of electrochemical area.
