Abstract
The present disclosure provides a method of graphene exfoliation and/or stabilization. Both graphene and silica are mixed in an organic solvent to form a liquid precursor, which is then directed through an orifice formed by a metal cylinder and a flat metal plate. The metal cylinder is pressed against the flat metal plate by a high pressure. The high shear between the metal cylinder and the flat metal plate breaks down the thick layers of graphene to thin layers, which are stably dispersed in the gel formed by the silica.

A composition comprising graphene dispersed in a gel formed by silica, the composition prepared by a method comprising:
- providing a liquid precursor comprising both the graphene and the silica mixed in an organic solvent;
- and
- directing the liquid precursor through an orifice comprising a metal cylinder and a flat metal plate, wherein the metal cylinder is pressed against the flat metal plate, and the liquid precursor is directed through an opening on the flat metal plate to a position between the metal cylinder and the flat metal plate,
- wherein the composition has a viscosity of about 200,000 to about 600,000 centistokes.
An automotive wax composition comprising a composition comprising graphene dispersed in a gel formed by silica, the composition prepared by a method comprising:
- providing a liquid precursor comprising both the graphene and the silica mixed in an organic solvent;
- and
- directing the liquid precursor through an orifice comprising a metal cylinder and a flat metal plate, wherein the metal cylinder is pressed against the flat metal plate, and the liquid precursor is directed through an opening on the flat metal plate to a position between the metal cylinder and the flat metal plate.
