An organometallic approach was used to functionalize multiwalled carbon nanotubes with n-butyllithium. This procedure was repeated two more times to achieve a higher degree of multiwalled carbon nanotube functionalization. The functionalized nanotubes have been characterized by Fourier transform infrared and Raman spectroscopy, thermogravimetrical analysis, scanning electron microscopy and sedimentation studies. It was possible to form stable suspensions of the functionalized nanotubes in tetrahydrofuran and they were used to make nanotube polymer composites. The mechanical properties of these new nanotube polymer composites were tested and they were found to show an increase of up to 25% in their Young's moduli and up to 50% in their tensile strength over pure polystyrene.
采用有机金属方法用正丁基锂对多壁碳纳米管进行功能化。该过程重复了两次，以实现更高程度的多壁碳纳米管功能化。通过傅里叶变换红外光谱和拉曼光谱、热重分析、扫描电子显微镜和沉降研究对功能化的纳米管进行了表征。在四氢呋喃中形成功能化纳米管的稳定悬浮液是可行的，并且它们被用于制备纳米管聚合物复合材料。测试了这些新型纳米管聚合物复合材料的力学性能，发现它们的杨氏模量比纯聚苯乙烯提高了25%，拉伸强度提高了50%。
