Abstract:
1. A method for making a carbon nanotube film, the method comprising: (a) providing a carbon nanotube array grown on a substrate and fixing the substrate with the carbon nanotube array on a substrate holder; (b) drawing a carbon nanotube film from the carbon nanotube array, and adhering a first part of the carbon nanotube film to a first bar placed on a bar supply device; (c) stretching the carbon nanotube film by the first bar, and adhering a second part of the carbon nanotube film to a second bar positioned on the bar supply device; (d) suspending a third part of the carbon nanotube film between the first bar and the second bar over a supporting element, the supporting element is placed on a carrier device; and adhering the third part of the carbon nanotube film to the supporting element; and (e) separating the third part of the carbon nanotube film from the first part and the second part of carbon nanotube film, the third part of the carbon nanotube film adhered to the supporting element is obtained.
