Abstract: A novel and effective method was applied to the surface modification of carbon nanotubes (CNTs) by using element sulfur.The thiol groups were grafted onto the surface of CNTs by addition of sulfur radicals followed by reduction.The new method was simple and safe,with no destroy to the internal structure of CNTs,which was expected to be applied in more fields.Thiol-modified multi walled CNTs and thiol-modified single walled CNTs were prepared using this method.Fourier transform infrared spectroscopy (FT-IR),Raman spectroscopy,thermogravimetric analysis and X-ray photoelectron spectroscopy were used to characterize the thiol groups grafted in the surface of CNTs.
