Abstract The carbon nanotube is a new allotropt of carbon.The discovery and the preparation,the mechanism for the formation,the structure and properties of carbon nanotubes presented in the paper.Meanwhile,its potential applications and studying direction are probed into briefly. 碳纳米管是一种新型的碳的同素异形体。本文简述了碳纳米管的发现和合成方法，描述了它的结构特点和生成机理，并对其潜在用途和今后的研究方向略作探讨。 文摘来源 A new proposal for the definition and classification principles of carbon materials is put forth. As far as the proposal is concerned, allotropic carbons such as graphite, diamond and fullerene, carbyne are called carbons. The rich diversity of carbons is elucidated and the characteristic and functions of these carbons are compared. The application prospects of carbon nanomaterials, one of the new class carbon materials, are outlined with carbon nanotubes as the example. 赋于炭素材料新的定义,将碳的同素异形体石墨、金刚石、富勒烯、咔宾等统称为炭素材料,并对其多样性进行论述以及对特性和功能进行了比较。对以碳纳米材料为首的新型碳材料的应用前景做了前瞻性的预测。 文摘来源 Carbon nanotube was reviewed as a new kind of advanced materials. Unique properties of carbon nanotube were introduced. Some special methods were discussed for preparing carbon nanotube. Many interesting application fields were indicated which were the perspectives for further investigations. Carbon nanotube could be used as field-emission probes, reinforcements in composite materials, hydrogen storage materials, etc. 碳纳米管是一种新型的碳的同素异形体。本文简述了近年来碳纳米管在场发射、复合材料、储氢材料及医学等方面的应用研究的现状与进展,并对碳纳米管的应用前景进行了展望。 文摘来源 << 更多相关文摘
