Ordered Whiskerlike Polyaniline Grown on the Surface of Mesoporous Carbon and Its Electrochemical Capacitance Performance

Supercapacitor electrode materials must exhibit high specific capacitance and high-rate charge–discharge ability. The ordered whiskerlike polyaniline (PANI) reported here, which was synthesized in situ on the surface of mesoporous carbon by a novel process, is demonstrated to have these properties thanks to its ordered nanometer-sized “thorns” (see figure) and the V-shaped nanopores between them.
