Abstract

A methos for producing nanoplates derived from a layered material, includes the steps: (a) mixing particles of said layered material with a carrier liquid to form a dispersion of said particles in said carrier liquid; (b) pressurizing the dispersion to a pressure of at least 10 kpsi; and (c) forcing the dispersion along a microfluidic channel under said pressure, to apply a shear rate of at least 105 s−1 to said particles in the dispersion. Exfoliation of nanoplates from said particles is thereby caused. The nanoplates may be graphene nanoplates, for example. Steps (b) and (c) may be repeated for a number of cycles in order to promote exfoliation. The method may be carried out using a microfluidizer.
