Abstract

The invention relates to a carbon nano tube surface functionalization method. The method comprises the following steps of: performing surface coating treatment to a carbon nano tube through a dopamine hydrochloride biomimetic modification method, and performing surface functionalization grafting treatment to the dopamine-modified carbon nano tube through a second functionalization monomer. The method aims to improve the dispersibility of the carbon nano tube in a rubber matrix and the bonding performance of the carbon nano tube with a rubber interface, therefore, the problems of dispersing in the matrix and the poor interfacing bonding of the conventional non-modified carbon nano tube are solved; a series of problems such as damage to the carbon nano tube, environment pollution and complicated technical process, due to strong acid corrosion oxidation treatment in the conventional carbon nano tube surface modification method are prevented; and the technical process is simplified and the produced modified carbon tube is excellent in performance.

Description

technical field

[0001] The invention relates to a method for functionalizing the surface of carbon nanotubes, which aims to improve the dispersion of carbon nanotubes and the interface bonding performance with other materials, so that carbon nanotubes can exert more excellent performance when applied to the preparation of composite materials . Background technique

[0002] As we all know, since Lijima reported the discovery of carbon nanotubes in 1991, carbon nanotubes have become a research hotspot in the field of nano-functional materials because of their unique topology. Carbon nanotubes have super mechanical properties, high chemical and thermal stability, and good electrical properties. Quasi-one-dimensional quantum wires. Therefore, it has extremely broad application prospects in the fields of nano-devices, microelectronics, and functional composite materials. The reason why carbon nanotubes have so many advantages is mainly due to the sp between carbon atoms. 2 Hy...
