Abstract
A method for making a thermal interface material includes the steps of: (a) providing an array of carbon nanotubes formed on a substrate, the carbon nanotubes having interfaces defined therebetween; (b) providing a transferring device and disposing at least one low melting point metallic material above the array of carbon nanotubes, using the transferring device; and (c) heating the low melting point metallic material and the array of carbon nanotube to a certain temperature to make the at least one low melting point metallic material melt, then flow into the interspaces between the carbon nanotubes, and combine (e.g., mechanically) with the array of carbon nanotubes to acquire a carbon-nanotube-based thermal interface material.
