Polyaniline/c-MWNT nanocomposite and method for fabricating the same

The invention provides a carbon nanotube compound and method for producing the same. The method of the invention comprises the following steps. Firstly, Aniline-trimer and DMAc(dimethyl acetamide) solution are mixed to form a first solution. Secondly, Dianhydride and DMAc solution are mixed to form a second solution. The first solution and the second are mixed to form a third solution. Additionally, carboxyl-multiwall carbon nanotubes (c-MWNT), Diaminodiphenylether and DMAc solution are mixed to form a fourth solution. The third solution and the fourth are mixed to form a polyamic acid/CNT solution. Some polyamic acid/CNT solution is spread on a substrate and processed by a thermal treatment, and a carbon nanotube compound is eventually produced.
