Exfoliated graphite is obtained through the vaporization of intercalation compounds present in expandable graphite (Chung, 2015), this results in a material with low density, porous structure and high surface area.
How do you exfoliate graphite?
The exfoliation of flake graphite is performed in the tricomponent system made by a combination of ammonium persulfate ((NH4)2S2O8), concentrated sulfuric acid, and fuming sulfuric acid, acquiring a ∼100% yield of graphene nanosheets in 4 h at room temperature.
What is exfoliated graphene?
Abstract. Electrochemical exfoliation is a promising bulk method for producing graphene from graphite; in this method, an applied voltage drives ionic species to intercalate into graphite where they form gaseous species that expand and exfoliate individual graphene sheets.
