Problems solved by technology
However, the carbon nanotube array is very easy to damage during the direct transfer process. For example, the carbon nanotubes in the carbon nanotube array are prone to tilting, bending, and some carbon nanotubes will be entangled together, which will cause the surface of the carbon nanotube array Unevenness and increased defects affect the performance of carbon nanotube arrays

Abstract
The invention provides a transfer method of a carbon nanotube array, comprising: providing a carbon nanotube array, a first substrate and a second substrate, the carbon nanotube array is located on the surface of the first substrate, and the carbon nanotube array includes A plurality of carbon nanotubes are perpendicular to the surface of the first substrate, and the surface of the second substrate has a bonding layer; a pressure is applied to the surface of the carbon nanotube array, so that the carbon nanotubes in the carbon nanotube array are poured on the A carbon nanotube paper is formed on the surface of the first substrate; the second substrate is placed on the surface of the carbon nanotube paper; and the second substrate is peeled off to make the carbon nanotubes in the carbon nanotube paper and the carbon nanotube paper The first substrate is separated and bonded on the adhesive layer of the second substrate, and then the carbon nanotube array is transferred to the second substrate, and the carbon nanotubes in the carbon nanotube array are substantially perpendicular to the second substrate. the surface of the substrate.
Description
technical field [0001] The invention relates to a method for transferring a carbon nanotube array, in particular to a method for transferring a superparallel carbon nanotube array. Background technique [0002] Carbon Nanotube (CNT) is a hollow tube rolled from graphene sheets, which has excellent mechanical, thermal and electrical properties. The carbon nanotube array formed by the growth of multiple carbon nanotubes vertical to the substrate can better exert the excellent properties of carbon nanotubes such as electrical conductivity and thermal conductivity in the axial direction, and has a very wide range of application prospects. For example, it can be applied to field emitters , blackbody radiation source and many other fields. [0003] Since the shape of the carbon nanotube array is very easy to damage, the carbon nanotube array is usually fixed on a fixed substrate when the carbon nanotube array is stored, and then transferred to the target substrate during use. In...
