Abstract
The dopamine on surface of carbon nanotubes modified as the theme, overview of the current carbon nanotube surface modification of basic method and corresponding principle, introduce dopamine structure characteristics and application status, introduce the characteristics of dopamine hydrochloride and dopamine self polymerization process and the corresponding process control conditions, to introduce the dopa solution self-assembly of carbon nanotubes change process and characterization methods and the main change results. Carbon nanotubes because of its unique structure and excellent performance, and has attracted wide attention and has great application potential in many fields. Because of the insoluble in water and organic solvents, the carbon nanotube has greatly restricted its application. Therefore, the functional modification of carbon nanotubes has become a hot research topic. Next, the carbon nanotubes and their properties are introduced. The research progress of the modification of carbon nanotubes is discussed in detail, and the future research directions are also discussed. Based on the current status, put forward the research deficiency, and put forward the opinion.
Key words: dopamine, carbon nanotubes, surface modification

1 前言
自1991年碳纳米管发现以来,对于碳纳米管的研究越来越受关注。在碳纳米管的合成,结构性能以及应用都开展了广泛的研究。另外在纳米管化学以及纳米复合材料方面,如何利用纳米管的结构性能制备高性能的纳米复合材料也备受关注。
纳米复合材料指的是分散相尺度起码有一维小100纳米的复合材料,单壁碳纳米管的直径是一纳米到十纳米,多壁碳纳米管的直径是几十纳米到几百纳米,其长度为微米级。然而碳纳米管被认为是准一维纳米材料。碳纳米管复合材料尤其是聚合物基复合材料,主要是利用聚合物的加工性能和碳纳米管独特的机械,电气和热性能,通过复合效应得到的复合材料,具有优良的性能。
