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 3):
The method of  claim 2 , wherein the carbon nanotube population comprises semiconducting single-walled carbon nanotubes (s-SWCNTs) and metallic single-walled carbon nanotubes (m-SWCNTs), and wherein after the centrifuging step, the carbon nanotube composition is separated by wall number and by outer wall electronic type into at least four separation fractions, the at least four separation fractions comprising the first separation fraction, the second separation fraction, a third separation fraction comprising a carbon nanotube subpopulation comprising a higher percentage of s-SWCNTs than the carbon nanotube population, and a fourth separation fraction comprising a carbon nanotube subpopulation comprising a higher percentage of m-SWCNTs than the carbon nanotube population.
