Abstract
A dispersant for a carbon nanotube and a composition comprising the same are provided, wherein the dispersant is comprised of a structure including a head part composed of an electron-rich atom and an aromatic ring having a high affinity for the carbon nanotube and a tail part having an affinity for a dispersion medium, and thus exhibits excellent stabilizing and dispersing effects of the carbon nanotube in a variety of dispersion media including organic solvents, water or mixtures thereof. Use of the dispersant in accordance with the present invention enables convenient preparation of carbon nanotube compositions necessary for a variety of industrial fields such as emitters of field emission displays (FEDs), carbon nanotube inks, printable carbon nanotubes and the like.
