Water-soluble multi-walled carbon nanotubes (MWNTs) were obtained by functionalizing MWNTs with glucosamine after γ-ray irradiation. Products after each chemical treatment were characterized by FTIR and RAMAN spectroscopy. Elemental and TGA analyses of the modified MWNTs indicated that the concentration of functional groups bound on MWNTs increased with irradiation dose, due to increased defects of the MWNTs induced by γ-irradiation. Water solubility of MWNTs modified with glucosamine after irradiation enhanced considerably. The results provide a novel access for functionalizations and applications of carbon nanotubes.
