Carbon nanotubes, also known as buckytubes, have many unusual mechanical, electrical and chemical properties. In recent years, with the extensive researches on carbon nanotubes and nanomaterials, its broad application prospect has also been continuously demonstrated.
Since it has been discovered in 1991, carbon nanotube has attracted attention from over the world due to its unique structure and extraordinary properties. Its super mechanical properties, excellent field emission properties, high hydrogen storage performance has made its a hot spot in the field of nanomaterial.
So that it is very important to research the cost-effective and simple synthesis method of carbon nanotubes.
According to some researches, the synthesis of carbon nanotubes mainly includes arc process, laser ablation (evaporation), catalytic cracking method or catalytic chemical vapor deposition(CCVD) technique, as well as directional control growth method based on a variety of synthetic techniques, and so on.
