摘　　要：以聚四氟乙烯为原料,利用固相法对碳纳米管进行氟化,制备功能化的碳纳米管。采用红外光谱(FTIR)、X射线衍射(XRD)、X衍射光电子能谱(XPS)对氟化碳纳米管进行了表征。结果表明在碳纳米管表面生成了C—F键,成功地制取了氟化碳纳米管,氟原子的摩尔分数达到3.59%。此"固相法"不同于以剧毒单质氟气作为氟源的"气相法",它具有制备方法简单、操作安全的特点,对促进碳纳米管的改性和应用具有非常重要的意义。Fluorinated carbon nanotubes （ F-CNTs） were synthesized by solid-phase method using PTFE compound as the main raw material. The structures of raw CNTs and F-CNTs have been characterized by FTIR,XRD and XPS measurements. The results showed that C— F bonds were created on the surface of carbon nanotubes, and the fluorinated carbon nanotubes were successfully synthesized. The mole contents of fluorin atom can be reached 3.59 % . The new solid-phase technique is different from the gas-phase method which usually taken strong poisonous fluorine gas as the main raw material. The new solid-phase method had many advantages, such as simplicity, and safety, which is significant for improving the wide applications of carbon nanotubes.
