A new and efficient method for the thioamidation of single-walled carbon nanotubes (SWCNTs) has been introduced by direct addition of an intermediately generated nitrogen-based nucleophile. In this approach, there is a synergistic effect between benzonitrile, CaH2, and thioacetic acid leading to the formation of calcium thiolate which subsequently added to the sidewalls of the tubes. This finding was also confirmed when SWCNTs with benzonitrile moieties on their sidewalls were tested. The successful covalent functionalization of SWCNTs has been proven by thermogravimetric analysis, Raman, IR, and X-ray photoelectron spectroscopy techniques.
