Advanced technological uses of single-wall carbon nanotubes (SWCNTs) rely on the production of single length and chirality populations that are currently only available through liquid phase post processing. The foundation of all of these processing steps is the attainment of individualized nanotube dispersion in solution; an understanding of the colloidal properties of the dispersed SWCNTs can then be used to design appropriate conditions for separations. In many instances the size of the nanotube, particularly its length, is especially active in determining the achievable properties from a given population, and thus there is a critical need for both measurement technologies for length distribution and effective separation techniques. In this Progress Report, we document the current state of the art for measuring dispersion and length populations, including separations, and use examples to demonstrate the desirability of addressing these parameters.
