▎ 摘　　要

NOVELTY - Automatic device comprises a carbon dioxide storage device, a conveying device, a reaction device, a waste gas processing and recycling device (9), the reaction device comprises a multi independent spaces, the adjacent spaces are connected by a control door (20), the space at two ends of the reaction device is an automatic sample feeding chamber (31), an automatic sampling chamber (32), and a multi independent temperature control chambers and an automatic sample feeding chamber. The reaction device further comprises a reaction kettle (4), which is provided in the automatic sample feeding chamber, an automatic sampling chamber and a multi independent temperature control chamber can move. The self-locking ventilating device and the ultrasonic processor is passes through the sealing port. The self-locking ventilating device and the waste gas processing and recycling device are orderly connected through pipeline. USE - The automatic device is useful for preparing graphene composite material by ultrasonic auxiliary supercritical fluid (claimed). ADVANTAGE - The automatic device can solves the problems that the existing graphene composite material preparation device is complicated and difficult to operate; has low automation, high preparation cost, and low output, and is difficult to meet the problems of high-quality and industrialized preparation of graphene composite materials. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the automatic device for preparing graphene composite material by ultrasonic auxiliary supercritical fluid. Reaction kettle (4) Recycling device (9) Control door (20) Automatic sample feeding chamber (31) Automatic sampling chamber (32)
