New Progress on Studies of Carbon Nanotubes' Purification Technology Jiang Zhaoyang, Li Jiajun, Zhao Naiqin*, Liu Baohua Abstract As a new material, carbon nanotubes have been
attracted wide attention because of its distinctive molecular structure and performance.
Impurities such as amorphous carbon etc. usually exist in the carbon nanotubes newly
produced. It brings great inconveniece to its property and application research. The
purification technique of carbon nanotubes has been an important task in the field of
carbon nanotubes research. This paper reviews the typical purification methods of
mutil-wall carbon nanotubes and single-wall carbon nanotubes, and the purification
mechanism. 碳纳米管纯化技术研究新进展 姜召阳 李家俊 赵乃勤* 刘保华(天津大学材料学院 天津 300072) 摘要 碳纳米管(CNTs)是一种新型的碳材料，其独特的分子结构和性能引起了人们的广泛关注，而新制备的CNTs往往存在无定形碳等多种杂质，给CNTs的性质表征和应用研究都带来了很大的不便，CNTs的纯化已经成为CNTs研究领域的一个重要课题。本文综述了目前多壁碳纳米管和单壁碳纳米管的几种纯化方法及其相关机理。关键词 碳纳米管 纯化 机理 姜召阳 男，25岁，硕士生，现从事碳纳米管的研究工作。*联系人 E-Mail:nqzhao@tju.edu.cn天津市产业化专项基金资助项目 2002-07-05收稿，2002-11-05修回 |
