Polyacrylonitrile-derived carbon particles with uniform size and high porosity were synthesized and their capacitor properties were investigated. The carbon particles were simply prepared just by carbonizing and activating monodisperse polyacrylonitrile particles which were synthesized by polymerization of acrylonitrile in the mixture of methanol and N,N-dimethylformamide. The electrochemical measurements revealed that the carbon particles electrode maintained large specific capacitance even at high charge-discharge current densities.
