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.
