Abstract
The present invention relates to a method for making a Pickering emulsion, the method comprising: exfoliating a non-silicate layered 3D material in a solvent to produce particles of a non-silicate unfunctionalised 2D material; forming a dispersion of the particles of the 2D material in a first liquid phase; adding a second liquid phase; and homogenising the dispersion of the 2D material in the first liquid phase with the second liquid phase to form a Pickering emulsion comprising the first liquid phase, the second liquid phase, and the particles of the 2D material.

A method for making a Pickering emulsion, the method comprising:
- (a) exfoliating a non-silicate layered 3D material in a solvent to produce particles of a non-silicate unfunctionalized 2D material;
- (b) removing at least about 50 wt. % of the solvent and then adding a first liquid phase to form a dispersion of the particles of the 2D material in a first liquid phase;
- (c) adding a second liquid phase and homogenizing the dispersion of the 2D material in the first liquid phase with the second liquid phase to form a Pickering emulsion comprising the first liquid phase, the second liquid phase, and the particles of the 2D material.
