Effect of Annealing Temperature on Polypyrrole Super Capacitive Behaviour

Abstract

Polypyrrole was synthesized by using potentiostatic electrodeposition method. Polypyrrole deposits on stainless steel for 25 min and it annealed at 500 c, 700 c, 1000 c and 2000 c, the effects of annealing temparature on polypyrrole morphology were studied by using scanning electron morphology technique. Similarly the super capacitive behaviour of polypyrrole was studied using cyclic voltammetry and charging-discharging technique. Maximum specific capacitance 62.87 F/gm is obtained at 700C. Keywords: potentiostatic, cyclic voltammetry, annealing temparature, polypyrrole, electrodeposition, stainless steel.
