Water-Soluble Single-Walled Carbon Nanotubes
Poly(aminobenzene sulfonic acid) and poly(ethylene glycol) functionalities are covalently attached to single-walled carbon nanotubes yielding water-soluble carbon nanotubes with a solubility of about 5mg/mL.
Organic Soluble Single-Walled Carbon Nanotubes
Octadecylamine functionalized single-walled carbon nanotubes exhibit properties normally associated with molecular species such as solubility in organic solvents (THF, carbon disulfide, benzene, chloroform, toluene and methylene chloride) and solution-based chemical transformations.
Carboxylic Acid Functionalized Single-Walled Carbon Nanotubes
Carboxylic acid functionalized single-walled carbon nanotubes contain –COOH functionality along the length of the nanotube which can be derivatized with a variety of functional groups.
Amide Functionalized Single-Walled Carbon Nanotubes
Amide functionalized single-walled carbon nanotubes contain approximately 4 atom% of amide groups along the length of the nanotube and can be dispersed in DMF, acetone and alcohols, with mild sonication.
