| 摘要 |
Carbon nanotube suspensions or dispersions include carbon nanotubes and a functionalized non-native polycyclic aromatic group attached to a surface of the carbon nanotubes. The carbon nanotubes in the suspensions or dispersions are pretreated by exposing the carbon nanotubes to a solvent (such as N-cyclohexyl-2-pyrrolidone), an acid (such as concentrated sulfuric acid), and a non-native polycyclic aromatic group. The carbon nanotubes pretreated according to this method can be dispersed or suspended in a solvent to prepare high concentration suspensions, dispersions and/or inks for various applications. |
