Application of carbon nanotubes CNT:

1. Carbon nanotubes as field emission materials depend on their structural characteristics and mechanical and electrical properties. First, carbon nanotubes are good electrical conductors with particularly large current carrying capacity and can withstand large field emission currents. Second, the diameter of single-walled carbon nanotubes can be as small as about 2nm, and such a small size can have significant local electric field strength at its hemispherical end.

2. As long as a small amount of carbon nanotubes is added to conductive or antistatic plastics and polymer materials, the resistance will drop by more than three orders of magnitude, so it has antistatic function. The conductivity of carbon nanotubes is greatly improved by using carbon nanotubes in polymers to prepare conductive polymer molded products, which can realize electrostatic spraying.

3. Carbon nanotubes have excellent electrical properties; carbon nanotubes have good conductivity with axial extension, so they can be used as micron wires.

4. Carbon nanotubes have high strength characteristics and can be used as high-strength ultrafine fibers, as well as as reinforcement materials for other fibers, metals, ceramics, etc. Carbon nanotube-reinforced composites are considered to be the final entry form and have very broad application prospects in composite material manufacturing. Its unique conductive carbon nanotubes can be used in large-scale integrated circuits, superconducting wires, etc.

5. It can also be used in battery electrodes and semiconductor devices. In addition, carbon nanotubes are also good hydrogen storage materials and can be used as "tanks" for fuel hydrogen fuel vehicles.
