Abstract:
A method for making a carbon nanotube film includes the steps of: (a) adding a plurality of carbon nanotubes into a solvent containing metallic ions, and flocculating the carbon nanotubes to get a floccule structure with the metallic ions therein; (b) reducing the metallic ions into metallic atoms, thereby the metallic atoms being attached onto outer surfaces of the carbon nanotubes to form a floccule structure of carbon nanotubes compounded with metal atoms; and (c) separating the floccule structure compounded with metal atoms from the solvent; and (d) shaping the floccule structure compounded with metal atoms to obtain/get the carbon nanotube film.

Abstract:
A method of preparing a carbon nanotube/polymer composite material is provided. The method includes (a) providing a carbon nanotube-based film and a pre-polymer solution; (b) placing the carbon nanotube-based film at a bottom of a container, and pouring the pre-polymer solution in the container; and (c) polymerizing the pre-polymer solution and simultaneously integrating the pre-polymer solution with the carbon nanotube-based film. As such, a carbon nanotube/polymer composite material, including the polymer-impregnated nanotube layer and an upper polymer layer, is obtained. A multi-layer composite can be produced by essentially repeating this process, using the upper polymer layer as the base layer for the formation of the next layer set thereon.
