纳米碳管分离提纯技术

较详细地介绍了当前国内外纳米碳管分离提纯的最新技术 ,并分别对各种可能具有应用价值的分离方法进行了评述。在综合分析目前国际上研究纳米碳管两大类截然不同的分离技术———化学提纯法和物理提纯法———的基础上 ,提出这方面研究应该综合利用物理分离和化学分离方法 ,达到既能得到高纯度纳米碳管 ,又能减少对纳米碳管的结构破坏的最终目的。最后 ,对各国的纳米碳管分离研究现状进行了进一步的讨论。

PURIFICATIONS OF CARBON NANOTUBES

Several purification techniques for both multi| (MWNTs) and single|wall carbon nanotubes (SWNTs) are introduced in details.These techniques are classified into two parts: chemical methods and physical methods.Although the purified nanotubes is always partly destructed by chemical methods,it is no doubt that chemical methods are more efficient to purify crude nanotubes sample than physical methods.This paper points out that a combination of chemical methods and physical methods should be used in order to get high purified and low destructive carbon nanotubes.In the end,the authors also describe the latest research horizon on the purification of carbon nanotubes in China and other countries.
