▎ 摘　　要

NOVELTY - Device is mainly composed of an autoclave body, a heating jacket, a rotating support and a data monitoring system. The heating jacket is located outside the autoclave body, and the rotating support supports and rotates the autoclave body. The data monitoring system obtains real-time data inside the autoclave body. USE - Device for online monitoring of graphene hydrogel preparation. ADVANTAGE - The graphene hydrogel is self-assembled inside the kettle body, and the data monitoring system records the temperature and pressure inside the kettle body in real time, and observes the graphene hydrogel morphology changes through the visual glass. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of device for online monitoring of graphene hydrogel preparation.
