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.
