Abstract
A method for dispersing nanotubes, comprising forming a nanocomposite solution with associated nanotubes and nanoplatelets, mixing a surfactant to the nanocomposite solution, separating the nanocomposite in solution, wherein the nanotubes remain suspended in the surfactant solution, and isolating the nanotubes in solution. In certain instances, the method further comprises functionalizing the nanotubes in solution.
Claims19
A method, comprising:
- forming a nanocomposite solution, having at least one nanotube and at least one nanoplatelet, wherein the nanotube is exfoliated;
- mixing at least one surfactant to the nanocomposite solution;
- separating a nanocomposite, wherein the nanotube remains suspended in the surfactant solution, and the nanoplatelet is precipitated from the nanotube and surfactant solution;
- and
- isolating the nanotube in solution, wherein isolating the nanotubes in solution comprises destabilizing or functionalizing the nanotubes in solution, and dispersing the nanotubes in a solvent, wherein functionalizing the nanotubes comprises mixing a solution containing amines, amides, ions, or other organic or inorganic groups, wherein the solution comprises sulfanilamide.
