Multi-wall carbon nanotubes (MWNTs) irradiated with γ-rays were subjected to chemical modification. Products from 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 increasing doses, due to defects created on the MWNTs by γ-ray irradiation. Solubility in acetone and DMF of the irradiated and chemically modified MWNTs enhanced considerably in comparison with the control (without irradiation). The study will be of help for exploring novel applications of functional carbon nanotubes.
