1. A method for separating planar nanomaterials by thickness, the method comprising:
centrifuging a boron nitride nanomaterial composition in contact with an aqueous fluid medium comprising a density gradient, wherein the boron nitride nanomaterial composition comprises one or more surface active components and a polydisperse population of planar boron nitride nanomaterials which is polydisperse at least with respect to thickness and has a mean thickness on the order of nanometers; and separating the boron nitride nanomaterial composition into two or more separation fractions each comprising a subpopulation of planar boron nitride nanomaterials from the polydisperse population, wherein the subpopulation of planar boron nitride nanomaterials in at least one of the two or more separation fractions has a mean thickness that is less than the mean thickness of the polydisperse population. |
