Abstract

In the preparation process of carbon nanotube-polyaniline composite material for super capacitor, polyaniline is deposited onto the surface of carbon nanotube. During charging and discharging, polyaniline produces electrochemical doping-dedoping effect to generate false capacitance and to increase the specific capacitance of carbon nanotube. By means of the selection of the deposited material and the control of the deposition process, the present invention prepares carbon nanotube-polyaniline composite material with excellent performance and greatly raised specific capacitance.
