Microwave-Assisted Bromination of Double-Walled Carbon Nanotubes

The first direct bromination of double-walled carbon nanotubes under microwave irradiation is reported. XPS analysis demonstrates the formation of covalent C−Br bonds with a loading of ∼5% w/w. Spectroscopic and microscopic (HR-TEM, TEM, SEM) analysis exclude any structural degradation of the CNTs framework, suggesting that this synthetic strategy could open new possibilities for designing novel functionalized CNTs.
