Transfer method of carbon nanotube array and preparation method of carbon nanotube structure

Abstract

The invention provides a method for transferring carbon nanotube arrays, which comprises forming a coating layer on the top of the carbon nanotubes of the carbon nanotube array away from the growth substrate; connecting the surface of the substitute substrate to the carbon nanotube array through the coating layer and the carbon nanotube array Combining away from the surface of the growth substrate, the surface of the substitute substrate is in contact with the cladding layer; and by moving at least one of the substitute substrate and the growth substrate, the substitute substrate is kept away from the growth substrate, thereby making the carbon The nanotube array is separated from the growth substrate and transferred to the replacement substrate, and the carbon nanotube array is transferred from the growth substrate to the replacement substrate, and maintaining the morphology of the carbon nanotube array still enables the carbon nanotube structure from The carbon nanotube arrays are drawn continuously.

Description

technical field [0001] The invention relates to a method for transferring a carbon nanotube array and a method for preparing a carbon nanotube structure, in particular to a method for transferring a carbon nanotube array and a method for preparing a carbon nanotube film or a carbon nanotube line. Background technique [0002] Carbon Nanotube (CNT) is a hollow tube rolled from graphene sheets, which has excellent mechanical, thermal and electrical properties, so it has a wide range of applications. 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 structure with a larger size. For example, a macroscopic film-like structure formed by multiple carbon nanotubes, namely Carbon Nanotube Film, and a macroscopic linear structure formed by multiple carbon nanotubes, namely Carbon Nanotube Wire. [0003] The Chinese invention patent with the notificat...

However, this not only lengthens the recycling period of the growth substrate, which is not conducive to the rapid growth of new arrays, but also easily destroys and scraps expensive monocrystalline silicon wafers during transportation.
