MnO₂ thin film was electrodeposited onto aligned carbon nanotubes(ACNTs) electrode in the electrolyte containing 0.2 mol/L Mn(CH₃COO)₂ and 0.1 mol/L Na₂SO₄ at pH=6.0.As observed by means of scanning electron microscopy,the resulting MnO₂ film on those nanotubes exhibited hole-like microstru-cture.Such-prepared MnO₂-modified ACNTs nanocomposite was then characterized by cyclic voltammograms,charge-discharge curve and electrochemical impedance measurements etc.,and it showed excellent capacitive behavior between 0~0.6 V(vs.Ag/AgCl) in 1 mol/L KCl aqueous solution.The specific capacitance of the ACNT electrode was calculated to be 16 F/g before the MnO₂ film modification,and increased to 330 F/g after the MnO₂ film deposition due to the special Faradic capacitance of MnO₂.After scaning for 200 cycles,there was a little change for its cyclic voltammogram curve,indicating good reversible and capacitive property of the MnO₂-ACNTs composite.
