Abstract

A preparation method of a carbon nanotube composite line comprises the following steps: providing at least one carbon nanotube film; providing a substrate, and growing a graphene film on the substrate; compounding the carbon nanotube film with the surface of the graphene film far from the substrate; removing the substrate to form a carbon nanotube-graphene composite film; and rolling up the carbon nanotube-graphene composite film, and twisting to form the carbon nanotube composite wire.

Description

technical field [0001] The invention relates to a preparation method of a carbon nanotube composite wire. Background technique [0002] Carbon nanotubes are hollow tubes made of rolled graphene sheets. Carbon nanotubes have excellent mechanical, thermal and electrical properties, and their application fields are very broad. For example, carbon nanotubes can be used to make field effect transistors, atomic force microscope tips, field emission electron guns, nano templates, etc. The application of carbon nanotubes in the above technologies is mainly the application of carbon nanotubes on a microscopic scale, and the operation is difficult. Therefore, it is of great significance to make carbon nanotubes have a macroscopic structure and apply them macroscopically. [0003] Jiang Kaili and others successfully obtained a carbon nanotube line with a macro scale from a carbon nanotube array in 2002. For details, please refer to the literature "SpinningContinuousCarbonNanotubeYar...
