Abstract

A method for making a carbon fiber film includes suspending a carbon nanotube film in a chamber. A negative voltage is applied to the carbon nanotube film. A carbon source gas is supplied into the chamber, wherein the carbon source gas is cracked to form carbon free radicals, and the carbon free radicals are graphitized to form a graphite layer on the carbon nanotube film.
