Single-wall carbon nanotubes (SWNTs) have been functionalized by a diazonium method through both a classical thermal reaction and a microwave-assisted reaction. The functionalized SWNTs have been characterized by nIR-Vis-UV absorption spectroscopy, Raman spectroscopy, and thermal gravimetric analysis. The results show that SWNTs are covalently functionalized through both reactions and that the microwave-assisted reaction is more rapid. Moreover, optimal choice of the reaction time can prevent the microwave irradiation from the adverse effect of subsequently removing the functional groups on the SWNT surface.
单壁碳纳米管（SWNTs）已通过重氮法，采用经典热反应和微波辅助反应两种方式进行了功能化处理。已通过近红外-可见-紫外吸收光谱、拉曼光谱和热重分析对功能化的单壁碳纳米管进行了表征。结果表明，单壁碳纳米管通过这两种反应均实现了共价功能化，且微波辅助反应更为迅速。此外，反应时间的最佳选择可以防止微波辐射对随后去除单壁碳纳米管表面官能团产生不利影响。
