Abstract:
1. A method for making a conductive film, comprising: providing a carbon nanotube film defining a plurality of holes therein; attaching the carbon nanotube film on a substrate; adjusting a temperature of the carbon nanotube film in a range from about 7° C. to about 9° C. so that the carbon nanotube film is hydrophilic; dropping and rubbing a nanoparticle aqueous solution in the carbon nanotube film, the nanoparticles aqueous solution containing a plurality of nanoparticles, the nanoparticle aqueous solution filling the holes of the carbon nanotube film; and adjusting the temperature of the carbon nanotube film in a range from about 24° C. to about 26° C. so that the carbon nanotube film is hydrophobic and drying the carbon nanotube film to obtain the conductive film on the substrate; wherein in the conductive film, water in the nanoparticle aqueous solution is repelled by the carbon nanotube film and the nanoparticles in the nanoparticle aqueous solution are left and received in the holes.
