Problems solved by technology
[0004] However, since this invention needs to separate the first carbon nanotubes from the first substrate by ultrasonic waves, then immerse them in a dispersion solution for dispersion, and then apply them to the second substrate and bake them, the preparation method is cumbersome and the process is complicated.

Abstract
The invention provides a carbon nanotube composite structure. The carbon nanotube composite structure comprises a first carbon nanotube structure and a second carbon nanotube structure, wherein the first carbon nanotube structure comprises multiple carbon nanotubes which extend in preferred orientation along the same direction and are connected end to end through a Van der Waals force; and the second carbon nanotube structure comprises multiple carbon nanotubes which are arranged on one surface of the first carbon nanotube structure, the root part of each carbon nanotube in the second carbon nanotube structure is connected with the surface of the first carbon nanotube structure, and the end part of each carbon nanotube in the second carbon nanotube structure extends in a direction of being away from the first carbon nanotube structure.
Description
technical field [0001] The invention relates to a composite structure of carbon nanotubes. Background technique [0002] In 1991, researchers from Japan's NEC Corporation accidentally discovered carbon nanotubes, please refer to: "Helical microtubules of graphitic carbon", S. Iijima, Nature, vol.354, p56 (1991), because of the excellent characteristics of carbon nanotubes, their potential The application of carbon nanotubes has been widely concerned, especially in the field of electronics. Because the diameter of carbon nanotubes is extremely small, about a few nanometers to a dozen nanometers, electrons can be emitted from their tips under the action of a small electric field, so they can be used as field emission cathode. [0003] In recent years, various studies have been carried out in the field of nanomaterials and their applications, especially the growth methods and applications of carbon nanotubes. For example, the Chinese patent No. CN100568436 filed on October 12...
