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.
