碳纳米管的表面功能化修饰机理及方法研究

Current progress on the surface modification for carbon nanotubes

碳纳米管作为一种一维纳米材料具有优异的性能,但是由于自身结构导致的不溶性,以及易于团聚和缺乏表面功能基团等实际问题,限制了其应用范围,因此,碳纳米管功能化修饰是碳纳米管应用研究的重点领域,本文介绍了碳纳米管表面功能化的几种主要方法:机械分散功能化、共价功能化、非公价功能化等,结合国内外研究进展,对碳纳米管功能化修饰的机理及方法进行综述。

As a new kind of one-dimensional nano-materials, carbon nanotubes（CNTs）has excellent properties. But CNTs intrinsically tend to bundle or aggregate. The preparation of effective dispersions of CNTs presents a major impediment to the extension and utilization of CNTs. The techniques of surface modifications play a key role in the practical application of CNTs. In this paper, we introduce several kinds of surface modifications for the ef-fective dispersion of CNTs, mechanical surface modifications, covalent surface modifications and non-covalent surface modifications. Connect with the current progress on the surface modification of CNTs, we try to explore the mechanism and techniques for the CNTs.
