| Abstract: | Octadecanol modified multiple-walled carbon nanotubes, with octadecanol covalently bound to the nanotube surface, have been synthesized by bromination of the carbon nanotubes followed by nucleophilic substitution using octadecanol and sodium hydride. Scanning electron microscopy and transmission electron microscopy images show that the morphologies of the nanotubes are largely intact after functionalization. The brominated carbon nanotubes and octadecanol modified carbon nanotubes were characterized using energy-dispersive X-ray spectroscopy, Raman spectroscopy and Fourier transform infrared spectroscopy. The mechanism of nucleophilic substitution was discussed, and it is believed that the reaction occurs with an SN1 mechanism. |
