Dispersant for dispersing carbon nanotubes and carbon nanotube composition comprising the same
First Claim
1. A dispersant for dispersing carbon nanotubes comprising a head and a tail linked to the head wherein the tail comprises at least one repeating unit of Formula 1 below or at least one repeating unit of Formula 2 below, or is polyethylene oxide or polypropylene oxide;
- and the head comprises a substituted or unsubstituted C6-30 aromatic hydrocarbon group;
wherein m is from 3 to 30, and R is selected from the group consisting of C1-10 alkyl, alkenyl and alkynyl groups, wherein n is from 3 to 30.

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.
