摘要
1991年科学家首次发现了在石墨电极直流电弧放电中生成的直径仅在纳米量级的由纯碳原子构成的纳米碳管。其独特的由石墨面卷曲而成的中空圆柱形一维晶体结构不仅丰富了人们对碳物质的了解,而且其潜在的应用价值也将给纳米材料科学领域带来极大的影响。本文概略地介绍了纳米碳管的发现过程和国际上的一些研究成果。着重显示了电子显微术特别是高分辨电子显微术在整个发现和结构确定过程中的突出作用。同时也将简要地介绍纳米碳管的生产,物理性质及应用前景方面的研究。
Carbon nanotubes were first discovered in 1991 by using transmission electron microscopy (TEM). The structure of the carbon nanotube can be regarded as a hollow cylinder rolled up by a graphene sheet. This pure carbon-contained texture not only opens a new understanding on carbon materials but also brings a big impact to material science in nanometer scales. In this paper, we will briefly review the discovery and structural characteri-zation of the carbon nanotubes with a particular emphasis on the critical role of TEM, especially high-resolution electron microscopy in the studies. Synthesis,properties and potential applications will also be introduced.
