A rapid and efficient method to prepare exfoliated graphite by microwave irra…

Abstract. Exfoliated graphite materials had been rapidly and efficiently prepared by microwave irradiation in a short time (about 4 min including 3 min mixing and 1 min microwave irradiation). The promotion of the intercalation by microwave irradiation was proven by X-ray diffraction. With increasing content of oxidant and intercalation agent, the expanded volume of exfoliated graphite inc…
