Technical Field

[0002] Carbon nanotubes, also known as buckytubes, are a unique one-dimensional quantum material with radial dimensions measured in nanometers and axial dimensions measured in micrometers, with both ends essentially sealed. Carbon nanotubes are primarily composed of several to dozens of layers of coaxial circular tubes of carbon atoms arranged in a hexagonal pattern. The distance between layers is fixed, approximately 0.34 nm, and the diameter is generally 2 to 20 nm. Depending on the axial orientation of the carbon hexagons, carbon nanotubes can be classified into three types: zigzag, armchair, and helical. Helical carbon nanotubes exhibit chirality, while zigzag and armchair carbon nanotubes do not.

The raw material gas needs to be heated before carbon nanotube production. Once the heating temperature is insufficient or too high, the production quality of the carbon nanotubes will be seriously affected. In addition, if the protective gas and the raw material gas are not fully mixed, the production quality of the carbon nanotubes will be greatly reduced, which will have an adverse impact on the production of carbon nanotubes.
