Abstract
A method for making carbon nanotube array includes providing a carbon nanotube array formed on a surface of a substrate. The carbon nanotube array is stripped from the surface of the substrate. The carbon nanotube array is suspended in an inert gas environment or a vacuum environment. A temperature of the carbon nanotube array can be in a range from about 200° C. to about 2400° C. by heating the carbon nanotube array. In a state of heating the carbon nanotube array, a plurality of carbon nanotubes of the carbon nanotube array is selected and a carbon nanotube film is pulled out by a drawing tool.
