▎ 摘　　要

NOVELTY - The device has a mobile platform (7) that is provided with a reaction chamber (9) filled with deionized water solution. A graphite solid target (18) is located in the deionized water solution in the reaction chamber. One side of the graphite solid target and an inner wall surface of the reaction chamber are provided with a third rotating shaft (4) and a second rotating shaft (13). The second rotating shaft is located above the water solution in the reaction chamber. The third rotating shaft is located in the second rotating shaft under the de-ionized water solution. A plane of the second rotating shaft is equipped with a first rotating shaft (11). The third rotating shaft is wound on a second copper foil (5). The second copper foil is fixed on the first rotating shaft after passing through the second rotating shaft from the third rotating shaft. An upper end of the reaction chamber is provided with a pulse laser device (26). USE - Device for preparing graphene by laser liquid phase irradiation. ADVANTAGE - The experiment time is saved, and the graphene preparation efficiency is improved. The accuracy and continuity of experiment are ensured. The utilization of the preparation efficiency of graphene and graphite solid target are greatly improved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing graphene by laser liquid phase irradiation.
