This patent has priority going back to May 30, 2003 and includes some basic claims for carbon nanotube-polymer composites. Claim 1 reads:

1. A composite material comprising

nanotubes; and

a polymer matrix wherein the nanotubes and polymer interact in an ordered fashion at an interfacial region so that the polymer wraps around the nanotubes, said region comprising a coating of polymer on the nanotubes in a crystalline or semi crystalline form, the interfacial region being between 5 and 160 nm in width.
