Problems solved by technology
Generally, carbon nanotubes in carbon nanotube aggregates have no fixed orientation. When the shear force is large during the dispersion process, the carbon tubes will be cut into shorter lengths. Agglomerates cannot be effectively de-agglomerated, resulting in a decrease in the dispersion effect

Description
technical field [0001] The invention relates to the field of chemical equipment, in particular to a dispersed arrangement of carbon nanotubes. Background technique [0002] Carbon nanotubes are one-dimensional nanomaterials, mainly composed of carbon atoms arranged in hexagons to form coaxial tubes with several to dozens of layers. The radial size of carbon nanotubes is generally on the order of nanometers from 2 to 100 nm, and the aspect ratio can reach more than ten million. Carbon nanotubes have good mechanical properties, their tensile strength reaches 50-200GPa, which is 100 times that of steel, but their density is only 1 / 6 of that of steel, which is an order of magnitude higher than that of conventional graphite fibers; its elastic modulus can reach 1TPa, It is equivalent to the elastic modulus of diamond and about 5 times that of steel. For carbon nanotubes with a single-walled ideal structure, the tensile strength is about 800 GPa. Since the structure of carbon n...
