▎ 摘　　要

NOVELTY - Composite phase-variable material based on aluminum foam comprises foamed aluminum metal layer and graphene layer are alternately disposed in layered structure, and the foamed aluminum metal layer comprises phase change material. USE - Used as composite phase-variable material based on aluminum foam. ADVANTAGE - The material: avoids low heat conduction efficiency and easy liquid leakage; and achieves purpose of improving heat conduction efficiency and reducing leakage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for heat storage package prepared by sealing the composite phase change material with a package.
