Abstract
A method for making carbon nanotube composite film is provided. An original carbon nanotube film includes carbon nanotubes joined end to end by van der Waals attractive force. The carbon nanotubes substantially extend along a first direction. A patterned carbon nanotube film is formed by patterning the original carbon nanotube film to define at least one row of through holes arranged in the original carbon nanotube film along the first direction. Each row of through holes includes at least two spaced through holes. The patterned carbon nanotube film is treated with a polymer solution. The patterned carbon nanotube film is shrunk into the carbon nanotube composite film.
