Patent ID: 8501529

Claim:
A method of doping carbon nanotubes, the method comprising: preparing an oxidizer solution comprising an oxidizer and an organic solvent; and doping carbon nanotubes using the oxidizer solution, wherein the oxidizer is a compound of chemical formula 1: where M is hydrogen, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 7 -C 30 arylalkyl group, a substituted or unsubstituted C 7 -C 30 alkylaryl group, Ag, Li, Cs, K, NO, NO 2 , or ClCO, and R 1 and R 2 are each independently a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 1 -C 20 heteroalkyl group, a substituted or unsubstituted C 2 -C 20 alkenyl group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 6 -C 30 heteroaryl group, wherein one more hydrogen atom in R 1 and R 2 is substituted for —CF 3 .
