Abstract
The present invention provides a method for transferring a carbon nanotube array, providing a replacement substrate and a growth substrate, the surface of the growth substrate has a carbon nanotube array; the replacement substrate is arranged on the second surface of the carbon nanotube array, and the There is a liquid medium between the substitute substrate and the second surface of the carbon nanotube array; changing the liquid medium between the substitute substrate and the second surface of the carbon nanotube array into a solid medium; by moving the substitute substrate and the second surface of the carbon nanotube array At least one of the growth substrates keeps the replacement substrate away from the growth substrate, so that the carbon nanotube array is separated from the growth substrate and transferred to the replacement substrate; The solid medium between the nanotube arrays, after removing the solid medium, the shape of the carbon nanotube array can still enable a carbon nanotube structure to be pulled out continuously from the carbon nanotube array.
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...
