Description

technical field [0001] The invention belongs to the technical field of slurry dispersion, and in particular relates to a high-efficiency disc type dispersion structure and a dispersion method for carbon nanotube slurry production. Background technique [0002] Carbon nanotubes, also known as bucky tubes, are one-dimensional quantum materials with a special structure (the radial dimension is on the order of nanometers, the axial dimension is on the order of microns, and both ends of the tube are basically sealed). Carbon nanotubes are mainly coaxial tubes with several to tens of layers of carbon atoms arranged in a hexagonal shape. Carbon nanotubes have attracted extensive attention due to their unique nanostructure and excellent mechanical, electrical, magnetic and optical properties. Because the carbon nanotube slurry has a certain viscosity, when the ordinary stirring and dispersing equipment disperses, it will deposit and cause uneven dispersion and a large amount of agg...

AI Technical Summary

Problems solved by technology

Because the carbon nanotube slurry has a certain viscosity, when the ordinary stirring and dispersing equipment is dispersed, there will be deposition, resulting in uneven dispersion and a large amount of agglomeration, so it is not suitable for the dispersion of carbon nanotube slurry. Dispersion with a general disc type dispersion structure can effectively solve the agglomeration phenomenon in the slurry, but its structure is simple, the dispersion efficiency is low, and it takes longer working time, which will affect the subsequent production
