碳纳米管的制备技术 纳米科技是20世纪80年代末、90年代初逐步发展起来的前沿性、交叉性的新兴学科。美国、日本、德国等发达国家已经为纳米科技研究投入了大量人力物力,其中日本在纳米管的制备领域成就最为突出。 碳纳米管的发现 1985年,美国科学家理查德·斯莫利首先发现C_(60)分子的富勒烯结构——像足球一样,呈中空网状结构。在其中填充不同的金属原子,就能够使它具有超导体或半导体性质,因而有可能成为取代硅半导体的新型电子材料和医用材料。在此基础
Preparation technology of carbon nanotubes Nanotechnology is the emerging, cross-cutting emerging disciplines that developed gradually in the late 1980s and early 1990s. Developed countries such as the United States, Japan and Germany have already invested a great deal of manpower and material resources in the research of nanotechnology, among which Japan has the most outstanding achievement in the field of the preparation of nanotubes. Discovery of carbon nanotubes In 1985, American scientist Richard Smalley first discovered that the fullerene structure of the C60 molecule, like a football, has a hollow network structure. Filled with different metal atoms can make it have superconducting or semiconducting properties, so it is possible to become a new type of electronic material and medical material instead of silicon semiconductors. Based on this
