Patent ID: 8530889

Claim:
A carbon nanotube composite comprising a carbon nanotube and a conjugated polymer comprising repeating units containing a fused heteroaryl unit having a nitrogen-containing double bond in the ring and a thiophene unit, wherein the conjugated polymer is attached to at least a part of a surface of the carbon nanotube, the conjugated polymer comprising repeating units containing a quinoxaline unit and a thiophene unit or the conjugated polymer has a structure represented by the general formula (1): Wherein R 1 to R 6 may be the same or different, and each represent hydrogen, an alkyl group, a cycloalkyl group, a heterocyclic group, an alkenyl group, a cycloalkenyl group, an alkynyl group, an alkoxy group, an alkylthio group, an arylether group, an arylthioether group, an aryl group, a heteroaryl group, a halogen atom, a cyano group, a formyl group, a carbamoyl group, an amino group, an alkylcarbonyl group, an arylcarbonyl group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an alkylcarbonyloxy group, an arylcarbonyloxy group, or a silyl group, adjacent groups of R 1 to R 6 may form a ring structure, A is selected from a single bond, an arylene group, a heteroarylene group except for a thienylene group, an ethenylene group and an ethynylene group, l and m represent an integer of 0 to 10, and l+m≧4, n represents a range of 2 to 1000, when l, m and n are 2 or more, each R 1 to R 6 and A may be the same or different.
