Abstract

A method for transferring a carbon nanotube array is disclosed. The carbon nanotube array has an ability to have a carbon nanotube structure drawn therefrom. The carbon nanotube array is transferred from a growing substrate to a substitute substrate, meanwhile the carbon nanotube array is still having the ability to have a carbon nanotube structure drawn from the substitute substrate. The substitute substrate is placed on the top surface of the carbon nanotube array. An adhesive layer is sandwiched between the substitute substrate and the carbon nanotube array. The substitute substrate is separated from the growing substrate, thereby separating the bottom surface of the carbon nanotube array from the growing substrate. A method for making a carbon nanotube structure is also disclosed.

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 structure formed by a plurality of carbon nanotubes, that is, a carbon nanotube film (Carbon Nanotube Film), and a macroscopic linear structure formed by a plurality of carbon nanotubes, that is, a carbon nanotube wire (Carbon Nanotube Wir...
