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

1. A method for fabricating a polyaniline/c-MWNT nanocomposite, comprising the following steps:

carboxylating at least one carbon nanotube to form at least one carboxylic carbon nanotube;

mixing the at least one carboxylic carbon nanotube with a solvent to form a first carbon nanotube solution;

mixing at least one aniline monomer with the first carbon nanotube solution to form a second carbon nanotube solution;

mixing an ammonium persulfate solution with the second carbon nanotube solution to form a third carbon nanotube solution;

air-extracting and filtering the third carbon nanotube solution to obtain the polyaniline/c-MWNT nanocomposite; and

cleaning and baking the polyaniline/c-MWNT nanocomposite.

2. The method of claim 1 , wherein the carboxylic carbon nanotubes of the polyaniline/c-MWNT nanocomposite disperse in the polyaniline.

3. The method of claim 1 , further comprising the following steps:

mixing at least one carbon nanotube with a sulfuric acid/nitric acid solution to form a mixed solution;

ultrasonic vibrating the mixed solution;

air-extracting and filtering the mixed solution to obtain at lease one carboxylic carbon nanotube; and

cleaning and baking the carboxylic carbon nanotubes.

4. The method of claim 3 , wherein the ratio of the sulfuric acid to the nitric acid of the sulfuric acid/nitric acid solution is 3:1.

5. The method of claim 3 , wherein the mixed solution is ultrasonic vibrated under the temperature range of 20±5° C.

6. The method of claim 1 , wherein the composition of the solvent is hydrochloric acid, namely, hydrogen chloride.

7. The method of claim 1 , wherein the ammonium persulfate solution is a mixture of ammonium persulfate and a first solvent.

8. The method of claim 7 , wherein the composition of the first solvent is substantially the same as that of the solvent.

9. The method of claim 1 , wherein the polyaniline/c-MWNT nanocomposite comprises an emeraldine base form of polyaniline.
