Abstract:
A method of separating carbon nanotubes by electronic type includes centrifuging a carbon nanotube composition in contact with a first fluid medium comprising a first density gradient; and separating the carbon nanotube composition into two or more separation fractions. The carbon nanotube composition comprises two or more non-ionic amphiphilic surface active components and a carbon nanotube population comprising double-walled carbon nanotubes having a semiconducting outer wall (s-DWCNTs), and double-walled carbon nanotubes having a metallic outer wall (m-DWCNTs). The two or more separation fractions comprise a first separation fraction comprising a carbon nanotube subpopulation comprising a higher percentage of s-DWCNTs than the carbon nanotube population, and a second separation fraction comprising a carbon nanotube subpopulation comprising a higher percentage of m-DWCNTs than the carbon nanotube population.

Claim (Index 5):
The method of  claim 3 , wherein the relative ratio of the two or more surface active components is selected to cause semiconducting carbon nanotubes to have a lower buoyant density than metallic carbon nanotubes of the same wall number.
