Patent ID: 8906338

Claim:
A method for making a carbon nanotube film, comprising: providing a carbon nanotube array grown on a top surface of a substrate and a rigid drawing device, the carbon nanotube array comprising a plurality of carbon nanotubes, and the rigid drawing device comprising at least one adhesive plane; adhering the at least one adhesive plane to the carbon nanotube array, wherein a border of the at least one adhesive plane closest to the substrate is a straight border; positioning the rigid drawing device so that the at least one adhesive plane is substantially perpendicular to the top surface of the substrate and in contact with the carbon nanotube array; positioning the rigid drawing device so that the straight border is parallel to the top surface of the substrate, and so that the straight border is between the top surface and an end of the plurality of carbon nanotubes and in contact with the carbon nanotube array, but not in contact with the substrate before pulling the rigid drawing device; and pulling the rigid drawing device at a speed along a direction away from the substrate, thereby pulling out at least one continuous carbon nanotube film.
