摘要

采用简单的机械化学方法制备了短而功能化的多壁碳纳米管。该方法的基本思想是在球磨机中，在CO、COCl2、Cl2、NH3、CH3SH等反应气体气氛下粉碎纳米管。在球磨过程中，纳米管的长度减少到200-300 nm，而比表面积增加了约20%，并且纳米管的内孔可以进入。

Mechano‐chemical functionalization of carbon nanotubes

Short, functionalized multiwall carbon nanotubes were prepared by a simple mechano‐chemical way. The fundamental idea of our method is breaking of the nanotubes under reactive gas atmosphere such as CO, COCl2, Cl2, NH3, CH3SH in a ball mill. During this ball milling procedure the tube length decreased to 200–300 nm, while the specific surface area increased by about 20% and the inner pore of the nanotubes became accessible.
