Carbon nanotubes are an emerging material that has had increasing industrial application in material reinforcement and great future potential in electronics, energy storage and conversion, and medicine1.- 4 The economic impact of carbon nanotubes has been mestimated at $2.7 billion by 20155. Discovered less than 25 years ago, carbon nanotubes are cylindrical, quasione dimensional structures of one (single-walled carbon nanotubes, SWCNT) or more (multi-walled carbon nanotubes, MWCNT) rolled-up sheets of grapheme. Carbon nanotubes have inner diameters from 0.7–2 nm and can have average lengths of several microns, depending on the method of preparation. Comprised solely of sp2 carbon, carbon nanotubes are strongly hydrophobic. They are very difficult to disperse in aqueous solutions as individual nanotubes; aggregation instantly occurs without amphiphilic surfactants present to fully coat the surface of the nanotubes.
