▎ 摘　　要

NOVELTY - Arbitrary shape three-dimensional graphene thermal conduction phase change composite material is prepared from graphene aerogel and phase change material, and its aerogel density is 20-100 mg/cm3. The composite material is provided in any shape having thermal conductivity of 2-11 W/(mK), and latent heat of phase change of more than 95% of the value of the phase change material itself. USE - Arbitrary shape three-dimensional graphene thermal conduction phase change composite material. ADVANTAGE - The arbitrary shape three-dimensional graphene thermal conduction phase change composite material has excellent dimensional stability, cycle stability, thermal conductivity, high phase transition latent heat, thermal conductivity, and latent heat of phase change. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing arbitrary shape three-dimensional graphene thermal conduction phase change composite material, which involves: (A) preparing graphene oxide dispersion by using graphite oxidation and exfoliation; (B) concentrating graphene oxide dispersion; (C) freeze-drying the obtained product to obtain a graphene oxide aerogel; (D) heat-treating the graphene aerogel at 500-3000 degrees C; and (E) filling phase change material into the obtained graphene aerogel to obtain the three-dimensional graphene thermal conduction phase change composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic photograph of the high-viscosity oxide graphene.
