<P>PROBLEM TO BE SOLVED: To provide a carbon nanotube dispersant, which can carry out an isolated dissolution of a carbon nanotube up to a single size in a solvent such as an organic solvent. <P>SOLUTION: The carbon nanotube dispersant includes as a repeat unit a constitution in which for example, a tricarbonyl benzene structure as shown in formulas (14) and (15) is a branching point, and comprises a hyperbranched polymer in which the weight-average molecular weight measured relative to polystyrene standards by a gel permeation chromatography is 1,000 to 2,000,000. Since the hyperbranched polymer is excellent in dissolution capability for carbon nanotubes, it is possible to obtain a composition in which a carbon nanotube is contained in an isolated dissolution state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
