▎ 摘  要

NOVELTY - Preparation of graphene aerogel continuous curved surface network, involves assembling graphene oxide into a film, and then placing it in a foaming agent for foaming, foaming, transferring to a good solvent of graphene oxide for soaking and self-assembly, and then performing high-temperature graphitization treatment after drying. USE - Preparation of graphene aerogel continuous curved surface network used in graphene aerogel composite material for thermal management, electromagnetic protection, flexible electronics, and energy storage (all claimed). ADVANTAGE - The preparation of a continuous curved surface network of graphene aerogel has reasonable control of the foaming and subsequent plasticization process, the surface tension of the solvent is used to enhance the interface bonding of the graphene aerogel skeleton after foaming. The method forms a continuous hyperboloid network of graphene overlapped surface to surface, which provides more transmission paths for internal carriers and phonons, and effectively reduces the contact thermal resistance/resistance between the sheets. The composite materials ensures excellent thermal and electrical conductivity at very low content, laying a foundation for the practical application of graphene composite materials in the field of thermal management, and promoting the industrial development of graphene composite materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of graphene aerogel composite material which involves adopting a graphene aerogel continuous curved surface network, immersing in a polymer substrate, and curing.
