However, the carbon nanotube film pulled from the carbon nanotube array is an ultra-thin film formed only by the carbon nanotubes being attracted to each other by van der Waals force. When stretching or connecting the carbon nanotube film , a little carelessness will cause the rupture of the carbon nanotube film, so this method is difficult for large-scale practical application

Abstract
The invention provides a method for preparing a carbon nanotube film, comprising the following steps: providing a plurality of carbon nanotube arrays respectively transferred to different substitute substrates, the morphology of the carbon nanotube array can make the carbon nanotube film from the carbon nanotube The carbon nanotube film is continuously pulled out from the array, and the carbon nanotube film includes a plurality of carbon nanotubes connected end to end; the multiple replacement substrates are arranged side by side, so that the sides of the plurality of carbon nanotube arrays are in contact with each other, and combined by van der Waals force, forming a stitched array, the area of the stitched array is larger than the area of the carbon nano-array; and pulling the carbon nanotube film from the stitched array.
Description
technical field [0001] The invention relates to a method for preparing a carbon nanotube film, in particular to a method for preparing a carbon nanotube film obtained by pulling from a carbon nanotube array. Background technique [0002] Carbon nanotubes are hollow tubular objects rolled from graphene sheets, which have excellent mechanical, thermal and electrical properties, so they have broad application fields. Because the size of a single carbon nanotube is nanoscale, it is difficult to use it. People try to use multiple carbon nanotubes as raw materials to make a macroscopic carbon nanotube film with a larger size. For example, a macroscopic film-like structure formed by a plurality of carbon nanotubes, such as a carbon nanotube film. The Chinese invention patent with the notification number CN101458975B discloses a carbon nanotube film obtained directly from a carbon nanotube array. This carbon nanotube film has good transparency, has a macroscopic scale and is self-s...
