▎ 摘　　要

NOVELTY - Device comprises a feeding unit, intercalation unit and stripping unit, where the graphite strip is conveyed by the feeding unit, orderly entering into the intercalation unit and the stripping unit. The stripping unit comprises an electrolytic tank II (51), temperature sensor II (64), temperature adjusting unit II (66) and alternating current power supply III (67). The electrolytic groove II is filled with electrolyte II (52). The temperature sensor II is placed in the electrolyte II, the two sides of the electrolytic cell II is provided with an electrode plate I (71) and an electrode plate II (72). The electrode plate I and the electrode plate II are connected with the alternating-direct current power supply IV (73). The stripping unit comprises an electric field sensor (65), where the electric field sensor is set in the electrolyte II between the electrode plate I and the electrode plate II. USE - Device used for stripping graphene by alternating electric field. ADVANTAGE - The device has high process automation degree and high safety performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using a device for exfoliating graphene by using an alternating electric field, which involves: (A) entering graphite strip the intercalation unit through the feeding unit for electrochemical pre-intercalation treatment to prepare the peeling precursor; and (B) entering graphite strips that have undergone the pre-intercalation treatment the stripping unit driven by the feeding unit, applying alternating electric field to both sides of the electrolytic cell II to strip to prepare graphene.
