▎ 摘　　要

NOVELTY - Composite phase change material package comprises composite phase change material is vacuum sealed with an aluminum plastic film comprising a foam metal layer and a graphene layer alternately arranged in a layered structure and the foam metal layer containing a phase change material. USE - Used as composite phase change material package. ADVANTAGE - The package solves problems of low heat conduction and easy liquid leakage after the combining foam metal and the phase change material in the prior art and improves heat conduction effect and reduces the leakage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a composite phase change material package, comprising filling phase change material in a foamed copper metal layer by a vacuum impregnation method, depositing in the foam by a deposition method, preparing graphene layer on the surface of the copper metal layer to obtain the composite phase change material, sealing composite phase change material and packaging in aluminum plastic film.
