New Development in the Synthesis of Single-Walled Carbon Nanotubes

Owning to the unique structure, the excellent physical and chemical properties, the superstrong mechanics performances and so on, carbon nanotubes had been attracting the interest of all over the world. As the basis of carbon nanotubes, single-walled carbon nanotubes(SWCNTs) have the better potential prospect in many fields, such as electron nano-devices, single electron devices, energy storage materials and so on. In this paper, the recent developments in the synthesis of SWCNTs were reviewed briefly, which included arc discharge, laser ablation, chemical vapor deposition and so on. At the same time, the crucial factors for the growth of SWCNTs were discussed.
