Multi-walled carbon nanotubes have been shortened by ball milling under ambient conditions. Detailed high-resolution TEM studies of the carbon nanotube ends showed a high-percentage of carbon nanotubes had partially or completely collapsed openings.

A simple mechano-chemical modification of multiwall carbon nanotubes is described. The use of ball-milling in specific atmosphere allows us to introduce functional groups like thiol, amine, amide, carbonyl, chlorine, etc. onto carbon nanotubes. The r

Chemical functionalization of carbon nanotubes (CNTs) is essential for many applications. Attachment of functional groups to nanotubes can dramatically increase the solubility of the nanotube material. Sidewall functional groups should react with pol
