Abstract

The invention discloses a preparation method of a high-dispersion carbon nanotube material, and belongs to the technical field of preparation of high-dispersion carbon nanotube materials. According to the preparation method, the problem that carbon nanotubes cannot be well dispersed when being added into other materials due to the agglomeration characteristic of a nano material, and then the performance exertion is hindered is solved. According to the invention, the in-situ growth of the carbon nanotubes is combined with the fiber material, so that good dispersion of the carbon nanotubes is realized, and the excellent performance of the carbon nanotubes is fully exerted. In addition, the preparation method provided by the invention is simple in preparation process and easy to operate, and is a convenient and effective preparation method.

Description

technical field [0001] The invention relates to a preparation method of a highly dispersed carbon nanotube material, belonging to the technical field of highly dispersed carbon nanotube material preparation. Background technique [0002] Carbon nanotube material is a one-dimensional carbon nanomaterial with excellent electrical conductivity, mechanical properties and many other properties. The unique properties make carbon nanotubes have various application potentials. As one of the materials with the best mechanical properties found so far, carbon nanotubes have extremely high tensile strength. Transparent bulletproof vests and other "black technology" products. In addition, some researchers have also developed a sensor fabric that can sensitively sense pressure changes by synthesizing carbon nanotube materials, which can play an important role in the field of sports training. People are also trying to make carbon nanotubes into transparent conductive films, which can be ...
