Technical Field

[0001] The utility model relates to the technical field of carbon nanotube dispersion, in particular to a carbon nanotube dispersion device. Background Art

[0002] Multi-walled carbon nanotubes, also known as buckytubes, are a one-dimensional quantum material with a special structure. Multi-walled carbon nanotubes are mainly composed of coaxial circular tubes with several to dozens of layers of carbon atoms arranged in a hexagonal pattern. Multi-walled carbon nanotubes are excellent fillers for permanent antistatic functional materials because of their unique nanostructure and the characteristics of high conductivity, low addition amount, and good mechanical properties of the product.

[0003] The defects of existing carbon nanotube dispersion devices are: the necessary conditions for uniformly dispersing carbon nanotubes mainly include breaking up carbon nanotube agglomerates, cutting long carbon nanotubes, and maintaining the dispersed state of carbon nanotubes. The specific dispersion methods are divided into two categories: physical methods and chemical methods. The chemical dispersion method mainly includes adding surfactants, strong acid and strong alkali washing, etc., while physical dispersion uses stirring and dispersion to disperse the carbon nanotubes. When the carbon nanotubes are dispersed by the dispersion device, the carbon nanotubes and dispersion liquid are usually placed in a barrel and then placed under the dispersion device. During this period, the barrel is not convenient for flexible adjustment or shaking, which causes the carbon nanotubes to be dispersed more slowly during the dispersion process, reducing the dispersion efficiency of the carbon nanotubes and also affecting the use effect of the carbon nanotube dispersion device; and when the material in the swingable barrel is stirred, the material is prone to splashing due to the influence of the swinging force and the stirring force. The splashing of the material affects the long-term and stable use of the dispersion device. For this reason, we propose a carbon nanotube dispersion device. Utility Model Content
