US Patent 7122165 - Ozone Functionalization of Nanotube Sidewall
http://www.freepatentsonline.com/7122165.pdf
Oxygen based functioalizaton of carbon nanotubes has been found useful for purposes of purification. However, usually the oxygen moiety attach to the endcaps or defect locations of the nanotubes. This patent discloses methodology to cover the sidewalls of nanotubes as well leading to more robust nanotube purification.
Claim 1 reads:
1. An ozonized carbon nanotube wherein about 3% to 30% of the sidewall carbon atoms have a primary ozonide attached.
