Abstract
A method for making carbon nanotube film includes providing a growth substrate having a first surface and a second surface opposite to the first surface. A catalyst layer is placed on the first surface. The growth substrate and the catalyst layer are placed in a reaction chamber. The carbon source gas and hydrogen are supplied into the reaction chamber at a growth temperature of a plurality of carbon nanotubes. An electric field is applied to the growth substrate, wherein an electric field direction of the electric field is from the first surface to the second surface. After the plurality of carbon nanotubes fly away from the growth substrate, the electric field is stopped applying to the growth substrate, and the carbon source gas and hydrogen are continually supplied into the reaction chamber.
