Progress of Study on Single Walled Carbon Nanotubes

Single wall carbon nanotubes （SWCNTs） is an advanced nanomaterial, the mainly preparation methods includes arc_discharge method, chemical vapor deposition（catalytic pyrolysis） and laser_vaporization, while CVD is an efficient synthesis methods of SWCNTs. For its characteristics, such as high strength while low density, unique optical, electromagnetic and thermal properties, and hydrogen-storage property, carbon nanotube can be extensively applied in avia- tion, aerospace, military and medicine industries.
