摘要：

Here, we report fluorination of multi-walled carbon nanotubes (MWNTs) via the surface wave microwave (SW-MW) plasma technique. We have investigated the change in the atomic and structures properties of fluorinated MWNTs using X-ray photoemission electron microscopy (XPS), Raman spectroscopy and transmission electron microscopy (TEM). The XPS study presents a semi-ionic boding character at a low concentration and a covalent bonding character at a high concentration, The Raman spectroscopy study shows an increase in disordered sp(3) hybridization in MWNTs with fluorine incorporation. High-resolution TEM study Of fluorinated MWNTs shows an induced defect oil the sidewall Without affecting the inner tubes' structure. (C) 2008 Elsevier B.V. All rights reserved.
