| 摘 要： | 以多壁碳纳米管(MWNTs)为原料,经自由基反应,制备了氰基改性的多壁碳纳米管,然后采用Al-NiCl2.6H2O-THF体系还原氰基得到了氨基化的碳纳米管。通过拉曼光谱仪、热重分析仪、X射线光电子能谱仪和透射电子显微镜对产物的结构与形貌进行了表征。结果表明:氨基通过共价键枝接在MWNTs的表面,氨基化多壁碳纳米管每1000个表面碳原子中有17.1个转化为氨基;该反应条件温和,反应时间短,且不破坏MWNTs的结构。

| Abstract: | Cyano functional groups were covalently attached to the surface of multi-walled carbon nanotubes(MWNTs) by free radical addition of AIBN, then Al-NiCl2·6H2O-THF system was used to reduce the cyano to obtain amino-functionalized carbon nanotubes. The structure and morphology of amino-functionalized MWNTs were characterized by Raman spectroscopy, thermal gravimetric analysis, X-ray photoelectron spectroscopy and transmission electron microscopy. The results showed that amino group was linked to the surface of MWNTs and approximately 17.1 of every 1 000 carbon atoms on the surface of MWNTs were grafted to amino groups. |
