▎ 摘　　要

NOVELTY - Preparing cetylamine three-dimensional graphene complex material, comprises preparing the three-dimensional graphene airgel by a hydrothermal method, and then compounding the hexadecylamine liquid and the three-dimensional graphene airgel by using a melting impregnation method. USE - The cetylamine three-dimensional graphene complex material is useful as energy storage material (claimed). ADVANTAGE - The latent heat value of the phase change material obtained by the method can reach 280kj/kg. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for hexadecylamine three-dimensional graphene complex obtained by the above preparation method
