Abstract
Disclosed herein is a method for exfoliating a laminar material to form an exfoliated material, in which the laminar material is ultrasonicated in a solution of a surfactant for sufficient time to form the exfoliated material. At all times during the ultrasonication the concentration of the surfactant in the solution is maintained sufficient to form a complete monolayer on the surfaces of the laminar material and the exfoliated material in the solution, or sufficient to sterically stabilize the laminar and exfoliated materials against aggregation.
