<p>A water dispersible carbon nanotube derivative comprises: (a) a carbon nanotube structure comprised of a carbon nanotube framework having first ionic groups covalently bonded thereto; and(b) a water-dispersibility enhancing agent which is an ionic form of an organic acid substituted with an amino group and having a maximum of fourteen carbon atoms, the ionic form providing second ionic groups of opposite charge to said first ionic groups. The derivative comprises a carbon nanotube structure ionically bonded to the water-dispersibility enhancing agent by the first and second ionic groups. Preferably, the organic acid is an amino acid, such as aspartic acid, arginine or taurine. The derivative may be used in an aqueous curable phenolic resin, which may be applied to a non-woven fibrous substrate.</p> |
