WebMechanical Exfoliation Graphene crystals are grown on a variety of substrates for varying applications. Graphene grown on insulators, such as SiO2, typically produces a film with small crystallites, whereas growth on the close-packed surfaces of metals yields highly crystalline films. WebLiquid-phase exfoliation (LPE) disperses graphite flakes into a solution using intercalating agents, which are molecules that place themselves between layers, and surfactants. It is supported by mechanical processing steps, like controlled ball milling, or solvothermal or sonochemical processes. This method generates a scalable form of graphene ...
