High performance electrochemical supercapacitor from electrochemically synthesized nanostructured polyaniline

摘要

Polyaniline nanowires were electrochemically deposited on stainless steel electrode at the potential of 0.75 V vs. SCE and characterized by cyclic voltammetry in 1 M H_2SO_4 electrolyte for supercapacitive properties. A high specific capacitance of 775 F g~(-1) was obtained at the sweep rate of 10 mV s~(-1). A long-term cyclic stability of the polyaniline nanowires demonstrated its implications for the high performance supercapacitors.
