Preparation of Carbon Nanotube/Polyaniline Composite by Organic Chemistry Synthesis

The aniline was inarched on the surface of the carbon nanotubes(CNTs) by a series of organic chemistry reactions.Then,the aniline on the surface of the CNTs was polymerized to polyaniline(PANI) by the in situ chemical polymerization.At last,a nanometer composite named as the CNTs/PANI composite was obtained.Constitution and morphology of the obtained CNTs/PANI composite were characterized by Fourier transform infrared spectroscope and scanning electron microscope.And the electrochemical performances of the obtained materials were tested by the cyclic voltammograms,galvanostatic charging/discharging,and electrochemical impedance spectroscopy.The results show that the obtained CNTs/PANI composite has excellent electrochemical capacitance used as the electrode material of the electrochemical super capacitor(about 152F/g in organic electrolyte),which is much more than those of the pure PANI,pure CNTs and the PANI/CNTs composite made by normal in situ chemical polymerization(about 65,25 and 80F/g in organic electrolyte).And the materials have appeared excellent application foreground in electrochemical energy field.
