▎ 摘  要

NOVELTY - Preparing mirabilite-based solid-liquid composite phase-change energy storage material involves mixing graphene oxide and cuprous oxide powder in a mass ratio of 1-2:1, uniformly mixing, adjusting the pH value to 10.5, and carrying out hydrothermal reaction to obtain modified nano-graphene composite cuprous oxide hydrogel. The hydrogel is washed, and freeze-dried to obtain blocky modified nano-graphene composite cuprous oxide aerogel. The aerogel is cut into a proper size, and then sequentially adopted the dipping and suction filtration technology to adsorb and shape the mirabilite-based phase change material. USE - Method for preparing mirabilite-based solid-liquid composite phase-change energy storage material. ADVANTAGE - The method enables to solve the supercooling degree and phase layering phenomenon of the mirabilite phase change energy storage material, and prolongs the service life of the phase change energy storage material.
