Chemical Attachment of Hydrogen Iodide to Carbon Nanotubes

A novel and facile method for preparing iodinated carbon nanotubes, with iodine and hydrogen simultaneously covalently bound to the surface of nanotubes, has been developed. The functionalized carbon nanotubes were fully characterized using Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, energy-dispersive X-ray (EDX) spectroscopy and thermogravimetric analyses. This is the first report on the successful functionalization of single-walled carbon nanotubes using hydroiodic acid.
