Abstract

Three novel methods for using microwave (MW) energy and water as a mild chemical agent for functionalization of carbon nanotubes were developed. In the first method we report the effect of MW irradiation on a dispersion of MWCNTs in water, in the second method we studied the exposing of MWCNT to MW irradiation in the presence of steam, and in the third method we used MW oven generated plasma for functionalization of MWCNTs, and finally we compared our results with thermal oxidation and acid treatment (as two conventional methods for oxidative functionalization of carbon nanotubes). Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) were used to analyses effect of these treatments on MWCNTs.
