Abstract:
1. A non-bundled carbon nanotube produced by a process comprising: a) providing, in any order: bundled carbon nanotubes, and urea as a precursor of isocyanic acid and/or cyanate ion, said isocyanic acid and/or cyanate ion being capable of undergoing a polymerization reaction; b) mixing together the bundled carbon nanotubes with urea to produce a mixture, wherein said mixing further comprises: c) initiating a polymerization reaction of the isocyanic acid and/or cyanate ion to produce non-bundled carbon nanotubes, wherein the at least one aldehyde is added to the mixture before, and optionally during or after, initiating the polymerization reaction, wherein the non-bundled carbon nanotubes have functional groups comprising aldehyde groups on their surface and/or ends, wherein said polymerization reaction occurs at said functional groups, and wherein the non-bundled carbon nanotubes have a solubility in water or aqueous solution of up to approximately 10 g/L, and a solubility in methanol or methanolic solution of up to approximately 1 g/L.
