VARIABLE-DENSITY CARBON NANOTUBE FILM

摘要

A method for making a variable-density carbon nanotube film is provided. A drawn carbon nanotube film, including a number of carbon nanotubes aligned along an aligned direction, is prepared. A number of thin regions are formed in the drawn carbon nanotube film along the aligned direction by reducing density of carbon nanotubes in each of the plurality of thin regions. A variable-density carbon nanotube film is provided and includes a number of thin regions and at least one normal region having a density of carbon nanotubes greater than that of the thin regions. The at least one normal region includes a number of carbon nanotubes substantially aligned along an aligned direction. The thin regions are arranged in the form of at least one row extending along the aligned direction.

1. A variable-density carbon nanotube film comprising:
a plurality of thin regions; and at least one normal region comprising a plurality of successively oriented carbon nanotubes joined end-to-end by Van der Waals attractive force therebetween, and the carbon nanotubes substantially aligned along an aligned direction; wherein the at least one normal region has a density of carbon nanotubes greater than that of the plurality of thin regions, and the plurality of thin regions are arranged along the aligned direction.
