US Patent 7197804 - Aligning carbon nanotube in copper conductor


This patent from The Aerospace Corporation takes advantage of the thermal conductivity of carbon nanotubes to form heat sinks by rolling the nanotubes into alignment on a copper sheet. Claim 1 reads:

1. A method of manufacturing thermal conductor sheet, the method comprising the steps of, mixing copper and carbon fibers together in a mixture at a predetermined ratio, and rolling the mixture to flatten the thermal conductor into a sheet with the carbon nanotubes being aligned within the plane of the sheet of the thermal conductor.
