Abstract
The present invention discloses a dispersant for carbon nanotubes having excellent dispersion ability and to a carbon nanotube composition including the dispersant. In the dispersant, the heads and tails of the dispersant are regioregularly arranged in one direction, and the structural properties of the dispersant are controlled such that the ratio of heads to tails is 1 or more, thereby effectively stabilizing and dispersing carbon nanotubes in various dispersion media, such as an organic solvent, water, a mixture thereof and the like, compared to conventional dispersants.
