▎ 摘　　要

NOVELTY - Preparing phase change energy storage material with bean-pod structure comprises providing the liquid phase change material as the nuclear layer to print the ink, providing the graphene oxide dispersion liquid as the shell layer printing ink; and using the 3 D printing process, the inner layer of the nuclear layer printing ink intermittent injecting coaxial printing needle head, the outer layer of the shell layer printing ink continuously injecting coaxial printing needle head, and performing coaxial printing. USE - The phase change energy storage material with bean-pod structure is useful in the phase change energy storage systems or smart fabric field (claimed). ADVANTAGE - The phase change energy storage material: realizes the independent package of phase change material; has continuous preparation, and has high phase change latent heat. The method has simple process, good repeatability, with good cycle stability, namely 1000 times cold-heat cycle after coating rate can reach 100%, and has controllable phase change structure size and uniform size. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for phase change energy storage material with bean-pod structure, comprising reduced graphene and multi-phase change material particles, the phase change energy storage material is pod structure, and the multi-phase change material particles are encapsulated in the reduced graphene oxide.
