TWO DIMENSIONAL MATERIALS PRODUCED BY THE LIQUID EXFOLIATION OF BLACK PHOSPHORUS

摘要

A process for producing two-dimensional black phosphorus flakes is carried out by: (a) mixing three-dimensional black phosphorus particles with a polar organic solvent to form a liquid dispersion thereof; and then (b) agitating the liquid dispersion for a time and at an intensity sufficient to produce two-dimensional black phosphorus flakes from at least a portion of the three-dimensional black phosphorus particles; and then (c) optionally separating the two-dimensional black phosphorus flakes from the three-dimensional black phosphorus particles. Compositions produced from the process are also described.
