Carbon nanotube having improved conductivity, process of preparing the same, and electrode comprising the carbon nanotube

A method of doping carbon nanotubes, the method comprising:

• preparing an oxidizer solution comprising an oxidizer and an organic solvent;
• and
• disposing carbon nanotubes using the oxidizer solution,
• wherein the oxidizer is a compound of chemical formula 1:
• where M is hydrogen, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C7-C30 arylalkyl group, a substituted or unsubstituted C7-C30 alkylaryl group, Ag, Li, Cs, K, NO, NO2, or ClCO, and
• R1 and R2 are each independently a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C1-C20 heteroalkyl group, a substituted or unsubstituted C2-C20 alkenyl group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C6-C30 heteroaryl group,
• wherein one more hydrogen atom in R1 and R2 is substituted for —CF3.
