Abstract:

At present, CNTs can be a variety of methods in the system, including arc discharge, chemical vapor deposition and laser evaporation method, which arc discharge and chemical vapor deposition method is used in two wider. No matter what kind of prepared CNTs, not high purity, containing the catalyst particles or amorphous carbon particles, graphite particles and other impurities. These impurities mixed with CNTs, it is difficult to meet the research and application needs of CNTs, and thus the study of CNTs purification is necessary. CNTs are made of carbon atoms to SP2 hybrid-based, mixed with SP3 hybrid built into the ideal structure, it can be seen as a sheet of graphene rolled into a cylinder. Therefore inevitable graphite excellent intrinsic properties: such as heat transfer, electrical conductivity, heat resistance, corrosion resistance, thermal shock resistance, lubricity, and biocompatibility, such as a series of excellent performance. In conclusion, CNTs unique structure gives superior performance and broad application prospects
