Abstract
A method for forming polymer carbon nanotube composites, the method comprising: contacting carbon nanotubes with ozone to functionalize the sidewalls of the carbon nanotubes with at least one oxygen moiety; and reacting the functionalized carbon nanotubes with at least one monomer or at least one polymer or copolymer to attach polymer chains to the sidewalls of the carbon nanotubes.
