Application for carbon nanotubes:
1. Carbon nanotubes as field emission materials, depending on its structural characteristics and mechanical and electrical properties. First, carbon nanotubes are good electrical conductors, particularly large current-carrying capacity, able to withstand large field emission current. Secondly, the single-walled carbon nanotube diameter can be as small as about 2nm, such a small size can have significant local electric field strength at its hemispherical ends.
2. Conductive or antistatic plastic, polymer material in just a small amount of carbon nanotubes, the resistance will decrease more than three orders of magnitude, it has anti-static function. The conductivity of the carbon nanotube, the carbon nanotubes used in the polymer to prepare a conductive polymer molded article greatly improved, enabling electrostatic spray.
3. The carbon nanotubes have excellent electrical properties; carbon nanotubes have an axial extension of good electrical conductivity, and therefore can be used as micro-wire.
4. The carbon nanotubes with high strength properties it can be used as high-strength ultra-fine fibers, and also other fibers, metals, ceramics and other reinforcing materials. Carbon nanotube reinforced composites is considered to be the ultimate form of entry, there is a very broad application prospects in the manufacturing of composite materials. Its unique conductive carbon nanotubes can be used for large scale integrated circuit, the superconducting wire rod.
5. Can also be used for battery electrodes and the semiconductor device. In addition, carbon nanotubes are good hydrogen storage material can be used as fuel hydrogen fuel car "storage tank."
