【 摘 要 】

The poor dispersion in aqueous solution limited the application of carbon nanotubes (CNTs) in biological field. Here we used DCC/DMAP as Catalysis to prepare lysine modified multi-walled carbon nanotubes (MWNTs). FT-IR and TGA demonstrated that lysine have been successfully grafted to MWNTs, EA showed that lysine graft rate up to 23.4%. The dispersion of lysine modified MWNTs was investigated by direct visual inspection and microscope observation, the result showed that lysine modified MWNTs can be dispersed in aqueous solution and keep stable for long time.
