碳纳米管及碳纳米管纤维的性能与应用

碳纳米管是由单层或多层石墨片卷曲而成的无缝纳米级管状壳层结构。扼要介绍了碳纳米管、碳纳米管纤维的合成方法及近几年来国内外制备的各种碳纳米管产品。碳纳米管、碳纳米管纤维由于其优良的力学、电学特性可以制成气体吸附体、生物模板、传动装置、增强复合体、催化剂载体、探测器、传感器、纳米反应器等产品，在航空、能源、医药、化学等技术领域广泛应用。

Properties and Application of Carbon Nanotubes and Carbon Nanotube Fibers

The carbon nanotubes consist of one or up to dozens of graphitic shells seamlessly wrapped into a cylindrical tube. Thenanofibers are the structure with the orientation of the graphitic lamella without central channel. The synthetic methods and products of carbon nanotubes and carbon nanotube fibers at home and abroad in recent years are summarized. Due to their excellent mechanical and electrical properties, carbon nanotubes and carbon nanotube fibers can be used as gas adsorbents, templates, actuators, composite reinfircements, catalyst supports, probes, chemical sensors, nano-reactors etc. They have a wide range of potential applications in various technological areas such as aerospace, energy, medicine and chemical industry.
