Prior approaches to exfoliating hBN have included chemical functionalization, bath sonication, and tip sonication . Our approach to exfoliate hBN is through a spontaneous thermodynamically driven spreading process. Previous work in our group has shown that graphite will lower the free energy of a system by spreading/exfoliating at an oil/water interface. Spreading the sheets at the oil: water interface lowers the interfacial energy of the system, providing a thermodynamic driving force for the exfoliation of graphite at the interface of the two immiscible phases. hBN has a similar stabilizing effect, allowing us to create water-in-oil emulsions stabilized by hBN sheets.
