Abstract

Phase transfer of multiwalled carbon nanotubes (MWNTs) from an aqueous phase into an organic phase is achieved. The transfer uses the hydrogen-bonding interactions between the disaccharide group of a sugar-based amphiphile and oxygenated functional groups on the surface of MWNTs. The dispersion of carbon nanotubes in a wide range of organic solvents is enabled, which represents the first example of solubilization of carbon nanotubes in organic solvents via hydrogen bonding interactions. © 2012 American Institute of Chemical Engineers AIChE J, 58: 2997–3002, 2012
