Abstract: | The results of the functionalization of multi-walled carbon nanotube surface by amines containing different substituents at the nitrogen atom, namely, primary n-hexylamine, secondary izadrine, and tertiary N-benzylmorpholine and dithiline, are presented. It was shown by NMR spectroscopy, thermal analysis, mass spectrometry, X-ray photoelectron spectroscopy, and elemental analysis that the interaction of primary and secondary amines with modified nanotubes results in the formation of a covalent bond with the nitrogen atom of amines, while the reactions with tertiary amines afford quaternary ammonium salts; diamine is attached covalently through both amine groups. |
