Abstract
A method for making carbon fiber film includes growing a carbon nanotube array on a surface of a growth substrate. A carbon nanotube film is pulled out from the carbon nanotube array, and pass through a reaction room. A negative voltage is applied to the carbon nanotube film. A carrier gas and a carbon source gas are supplied to the reaction room to form graphite sheets on the carbon nanotube film.
