Highly water-soluble multi-walled carbon nanotubes amine-functionalized by supercritical water oxidation†
Abstract
Multi-walled carbon nanotubes (MWNTs) have been amine-functionalized by eco-friendly supercritical water oxidation. The facilely functionalized MWNTs have high solubility (∼84 mg L−1) in water and 78% transmittance at 30-fold dilution. The Tyndall effect is also shown for several liquids.
