Liner structure of carbon nano tube and preparation method thereof

Abstract

The invention relates to a preparation method of a liner structure of a carbon nano tube. The method comprises the following steps of: providing a plurality of carbon nano tube arrays in coplanar arrangement; respectively drawing a plurality of carbon nano tubes from the plurality of carbon nano tube arrays to obtain a plurality of carbon nano tube films; converging the plurality of carbon nano tube films at a reference point; and merging and processing the plurality of converged carbon nano tube films. The liner structure of the carbon nano tube, which is prepared by using the method, has the diameter that is not limited to the size of a single carbon nano tube array and has favorable mechanical strength and toughness.

Description

technical field [0001] The invention relates to a carbon nanotube structure and a preparation method thereof, in particular to a carbon nanotube linear structure and a preparation method thereof. Background technique [0002] Carbon nanotubes are hollow tubes rolled from graphene sheets, which have excellent mechanical, thermal and electrical properties. Carbon nanotubes have a wide range of applications, for example, they can be used to make field effect transistors, atomic force microscope tips, field emission electron guns, nano templates and so on. However, the application of carbon nanotubes in the prior art is mainly the application of carbon nanotubes on a microscopic scale, and the operation is relatively difficult. Therefore, it is of great significance to make carbon nanotubes have a macroscopic structure and apply them macroscopically. [0003] The linear structure of carbon nanotubes is one of the macroscopic structures of carbon nanotubes. The linear structur...

However, the diameter of the nanofiber yarn in the above method is limited by the size of the nanofiber array

Since the substrate for growing the nanofiber array is a silicon wafer, and due to the limitation of the silicon wafer preparation process, larger-sized silicon wafers are difficult to obtain, and the growth area of ​​the nanofiber array is related to the size of the silicon wafer on which the nanofiber array is grown; That is to say, it is difficult to obtain nanofiber arrays with larger growth areas

Therefore, the diameter of the nanofiber yarn obtained by the above method is small, and the mechanical strength and toughness are not good enough, which limits the practical application of the nanofiber yarn
