Problems solved by technology

[0003] The existing macrostructures of carbon nanotubes mainly include carbon nanotube films. However, the specific surface area of ​​carbon nanotube macrostructures such as carbon nanotube films is large, and they show strong viscosity macroscopically. Once they come into contact with other objects, they will stick. Live and difficult to separate, so it brings great difficulties to preserve and transfer the macroscopic structure of carbon nanotubes, which greatly limits the further application of carbon nanotube structures such as carbon nanotube films in the macroscopic field

Abstract

The invention relates to a carbon nanotube film carrying structure, which comprises a body, wherein the body is provided with a surface; the surface of the body is provided with a carbon nanotube film carrying area; the carbon nanotube carrying area is provided with a plurality of depression structures; and the total depression area of the plurality of depression structures is larger than or equal to 80 percent of the area of the carbon nanotube film carrying area. The carbon nanotube film carrying structure is used for carrying a carbon nanotube film-shaped structure, and the carbon nanotubefilm-shaped structure can be completely separated from the carrying structure after being contacted with the carrying structure. The invention further relates to a method for using the carbon nanotube film carrying structure.

Description

technical field [0001] The invention relates to a carbon nanotube film bearing structure and a method of using the same. Background technique [0002] Carbon nanotubes are hollow tubes rolled from graphene sheets, which have excellent mechanical, thermal and electrical properties. Carbon nanotubes have a wide range of applications, for example, it can be used to make field-effect transistors, atomic force microscope tips, field emission electron guns, nano-templates, and more. However, at present, carbon nanotubes are basically applied at the microscopic scale, which is difficult to operate. Therefore, the assembly of carbon nanotubes into macroscale structures is of great significance for the macroscopic application of carbon nanotubes. [0003] The existing carbon nanotube macrostructures mainly include carbon nanotube films. However, carbon nanotube macrostructures such as carbon nanotube films have a large specific surface area and exhibit strong macroscopic viscosity....
