▎ 摘　　要

NOVELTY - The preparation of graphene-based multi-response stereotyped composite phase change material, involves (1) ultrasonically forming graphene oxide aqueous dispersion into uniform suspension, adding ammonium molybdate and thiourea, and magnetically stirring to form stable mixture, hydrothermally reacting the mixed solution to form composite graphene aerogel, freeze-drying the composite aerogel to obtain final composite graphene aerogel carrier, and (2) mixing phase-change material with carrier, placing phase-change material in vacuum oven to fully enter the phase-change material into carrier structure, and removing excess phase-change material on the surface. USE - Preparation of graphene-based multi-response stereotyped composite phase change material for thermal energy conversion and/or storage. ADVANTAGE - The graphene-based multi-response stereotyped composite phase change material is black block, and has enhanced stereotype effect, high phase change material loading, large phase change enthalpy, excellent cycle performance, and has strong light absorption and electrical conductivity, converts light energy and electrical energy into thermal energy for storage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite phase change material, which includes graphene-based multi-response stereotyped composite phase change material which is black bulk solid.
