| dc.description | Mesoporous carbon/conducting polymer composites have been synthesized by adsorption of different monomers (aniline, pyrrole, thiophene and 3-methyltiophene) in the gas phase onto the carbon surface, followed by oxidative chemical polymerization. The materials were tested as electrode material for electrochemical capacitors. The pore structure of the composites was examined byN2 isotherm adsorption at low temperature, showing that the synthesis of the polymers onto the carbon leads to a decrease of the BET surface value and the pore volume. The pore size distribution was unaltered independently of the polymer nature and concentration. Electrochemical performance of the composites was studied by cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy in 2.0 mol l-1 H2SO4. All composite electrodes show a stable cycle life in the potential range of 0 to 1V, the specific capacitance of carbon/polypyrrole composite electrode (83.8 F·g-1) being slightly higher than that obtained for the pristine mesoporous carbon electrode (77.9 F·g-1). The remaining carbon/polymer composites show lower specific capacitance than carbon only, due to their higher internal resistance (ESR). | |
