Abstract

Microwave radiation-assisted functionalization of single wall carbon nanoubes (SWNTs) to form highly soluble nanotubes has been demonstrated. After three minutes reaction, solubilities of more than 10 mg of nanotubes per milliliter of water and ethanol were obtained. The Raman spectrum of SWNTs obtained from its solution phase for the first time shows changes due to loss of quasi-one dimensionality of the backbone structure, whereas transmission electron microscopy indicates extensive debundling. Because of capillary effects, aligned SWNTs are obtained each time after evaporation of a drop of the solution on a hydrophobic substrate.
