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."
