US Patent 7197804 - Aligning carbon nanotube in copper conductor

http://www.freepatentsonline.com/7197804.html

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.
