Patent ID: 8499817

Claim:
A method for making a carbon nanotube metal composite comprising: (a) dispersing a plurality of carbon nanotubes in a solvent to obtain a suspension; (b) adding a plurality of metal powders into the suspension, agitating the suspension, and combining by adhering the plurality of carbon nanotubes in the solvent to the plurality of metal powders by electrostatic force between the plurality of carbon nanotubes and the plurality of metal powders; (b1) letting the suspension stand, settling the plurality of carbon nanotubes combined with the plurality of metal powders in a bottom layer of the suspension, and forming a boundary between an upper layer and the lower layer wherein the upper layer comprises mostly the solvent, the bottom layer comprises the plurality of carbon nanotubes combined with the plurality of metal powders which have been settled; and (c) reducing the solvent to obtain a mixture of the plurality of carbon nanotubes combined with the plurality of metal powders.
