摘 要:纳米材料的功能化修饰构成了现代纳米技术的重要组成部分。作为纳米材料的成员之一,碳纳米管不易分散或溶解于任何溶剂。为了改善碳纳米管的分散/溶解性能,对其进行必要的化学修饰是可行的途径。构成碳纳米管的芳香性碳—碳双键是其功能化修饰主体。利用有机化学碳—碳双键反应的基本理论知识,能指导碳纳米管的修饰,并可预测碳纳米管的形貌及电子性能改变规律。而碳纳米管的功能化修饰成果,也有助于增强难溶有机化合物的碳—碳双键反应特性和规律的理论基础。本文从近年的科研成果出发,从结构-性能角度深入探讨了不同修饰方法对碳纳米管形貌及结构的影响。基于碳—碳双键的加成反应有效保持了原始碳纳米管的形貌,更有利于修饰碳纳米管的广泛应用。Functionalization of nano materials consists of one of the important parts for modern nanometer technology. As a member of the nanomaterials, carbon nanotubes are not soluble/dispersive in any solbent. In order to improve the dispersion/solubility performance of carbon nanotubes, usually chemical functionalization is the most effective way. The aromatic C--C bonds are the main groups that could be modified. For guiding the functionalization of carbon nanotubes and for pre-determining morphology changes and electronic performances transformation during the functionalization procedure, the theory of aromatic C--C bond reactions in organic chemistry should be well utilized. The results obtaining from carbon nanotubes modification could promote the comprehension for the reaction characteristics of C--C double bonds of the insoluble compounds. Based on the scientific research result in recent years, the effects of different functionalization methods on carbon nanotubes" morphologies and structures are discussed from a structure-performance view. C--C double bond of carbon nanotubes could carry out addition reactions, keeping their original morphologies; therefore the functionalized carbon nanotubes are able to find their wider applications.
