| titleOfInvention | A kind of graphene/epoxy resin composite material based on lamellar anisotropy and preparation method thereof |
| abstract | The invention relates to a graphene/epoxy resin composite material based on lamellar anisotropy and a preparation method thereof. The graphene aerogel is obtained by bidirectional freezing of a mixed solution of graphene oxide and polyamic acid salt. , imidization, graphitization and other steps to obtain, and the epoxy composite material is obtained by controlling the compression of graphene aerogel and then compound curing with epoxy resin. The graphene/epoxy resin composite material has high thermal conductivity in the direction of graphene orientation, and at the same time its microscopic "brick and mud" structure imitating a shell endows the composite material with high fracture toughness. The controllable compression of aerogel solves the problem that the filling content cannot be increased when graphene aerogel is used as a thermally conductive filler; the lamellar structure constructed by the bidirectional freezing method solves the problem that the toughness of the composite material decreases when the filler content is too high . |
