US Patent 7253442 - Uncapped CNT thermal interface

http://www.freepatentsonline.com/7253442.html

This patent teaches improvements in the use of carbon nanotubes for thermal interfaces by removing the end caps of parallel carbon nanotubes embedded in a matrix. Claim 1 reads:

1. A thermal interface structure comprising: a macromolecular material; and a plurality of carbon nanotubes embedded in the macromolecular material; wherein the thermal interface structure has a first surface and a second surface opposite to the first surface; and each carbon nanotube is open at opposite ends thereof, and extends from the first surface to the second surface.
