Abstract

The invention relates to a composite structure of a carbon nano tube, comprising a carbon nano tube structure and a graphite structure which is filled in the carbon nano tube, wherein the carbon nano tube structure comprises a plurality of carbon nano tubes which are mutually connected by Van der Waals force. The graphite structure is compounded with the carbon nano tube structure by a carbon-carbon bond.

Description

technical field [0001] The invention relates to a composite structure of carbon nanotubes. 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] In 2002, Jiang Kaili and others successfully obtained a carbon nanotube line with a macroscopic scale from a carbon nanotube array. Please refer to the literature "Spinning Continuous Carbon Nanotube Yarns", Nature, V419...
