Graphitized Carboxylic MultiWalled Carbon Nanotubes (MWCNTs) are purified under inert gas for about 20 hours thermal treatment at 2800℃. The Carboxy functional groups on the surface of Carbon Nanotube (CNT) can not only improve their dispersion in solvents or polymer, but also act as reactive sites for further chemical modification.
