Abstract
The invention provides a method of functionalizing the sidewalls of a plurality of carbon nanotubes with oxygen moieties, the method comprising: exposing a carbon nanotube dispersion to an ozone/oxygen mixture to form a plurality of ozonized carbon nanotubes; and contacting the plurality of ozonized carbon nanotubes with a cleaving agent to form a plurality of sidewall-functionalized carbon nanotubes.
