Description

[0002] Carbon nanotubes have hexagonal walls, light weight, high strength, high toughness, high elastic modulus, and superior mechanical properties than general materials. Carbon nanotubes have unlimited possibilities and broad application prospects. They can not only be used to manufacture high-strength materials and fibers, but also can be used in biomedicine, electronics, energy and other fields.

[0003] Carbon nanotubes have a large specific surface area and fewer surface defects. Their hexagonal structure enables carbon atoms to form a large number of highly delocalized π electrons through sp2 hybrid orbitals. Adjacent CNTs attract each other and agglomerate under the action of π-π stacking, making them difficult to disperse and showing physical and chemical inertness. Therefore, before using carbon nanotubes to make materials, they need to be dispersed through a dispersion device. By dispersing the raw materials, each component is evenly distributed in the entire system to ensure the quality of the product, thereby improving the mechanical properties or conductivity of carbon nanotube composites.

[0004] However, during the stirring and dispersing process of carbon nanotubes, the carbon nanotubes will accumulate at the bottom of the dispersion device due to the influence of gravity, and the carbon nanotubes at the bottom will be stacked by the carbon nanotubes on the upper layer, resulting in uneven dispersion of the carbon nanotubes at the bottom, which in turn affects the subsequent use of the carbon nanotubes.
