| 摘 要： | 本文报道了微波辅助下，利用过氧化月桂酰分解得到的十一烷基，化学功能化修饰单壁碳纳米管。这种快速、高效的方法将反应时间缩短至10分钟，并得到了比传统回流方法具有更高接枝率的产物。利用傅立叶变换红外光谱(FT-IR)，热失重分析(TGA)，拉曼光谱，探究了不同的反应时间和微波功率对单壁碳纳米管的接枝率的影响。结果表明：过长的反应时间会导致部分的去功能化的发生，而过高的微波功率(大于900瓦)，则会将单壁碳纳米管上起初键连上的十一烷基剥落下来。分散性照片和高分辨率透射电子显微镜(HRTEM)照片显示出，功能化后的单壁碳纳米管与原始的碳管相比，在有机溶剂中的分散性有了明显的提高。

| Abstract: | Microwave‐assisted chemical functionalization of single‐walled carbon nanotubes, with undecyl groups decomposed from lauroyl peroxides was reported. This rapid efficient procedure reduced the reaction time to 10 min, and obtained the products with higher functionalized degree than that by the conventional refluxing method. The influence of different reaction time and microwave power on the functionalized degree has been explored by using FT‐IR, TGA and Raman analyses. The results show that longer treatment time will lead to partial defunctionalization, and higher microwave power (higher than 900 W) can reduce the functionalized degree by removing some initially‐attached functional groups. Dispersion stability images and HRTEM images show that the resulting SWNT has enhanced dispersivity in organic solvents compared to the pristine nanotubes. |
