Abstract
Disclosed herein is a dispersant for dispersing carbon nanotubes which comprises a head having a high affinity for carbon nanotubes and a tail having a high affinity for a dispersion medium. The head includes an aromatic hydrocarbon group with a high affinity for carbon nanotubes to prevent aggregation of the carbon nanotubes, thereby improving the dispersibility of the carbon nanotubes. Further disclosed is a carbon nanotube composition comprising the dispersant.
