▎ 摘　　要

NOVELTY - A three-dimensional cross-linked foam structure graphene reinforced resin composite material is prepared by selecting appropriate polyamino compound, adding graphene oxide solution to form graphene oxide and polyamino compound flocculate, centrifuging, freeze-drying, heating to obtain three-dimensional cross-linked foam structure of graphene, performing vacuum pressurizing or negative pressure flow molding method, pouring resin, filling a three-dimensional crosslinked structure of graphene porous foam, defoaming, heating, and curing. USE - Preparation of three-dimensional cross-linked foam structure graphene reinforced resin composite material (claimed). ADVANTAGE - The preparation process of three-dimensional cross-linked foam structure graphene reinforced resin composite material effectively improves the content of graphene while avoiding self-agglomeration.
