This study aims to explore the formation of a new type of building energy-saving material by combining inorganic hydrated salt phase change materials (PCMs) with expanded graphite (EG), to enable effective thermal exchange between the building envelope and the external environment, and enhance the thermal comfort of buildings. By dissolving a mixture (as PCM) of sodium thiosulfate pentahydrate (STP), sodium acetate trihydrate (SAT), and urea through a water bath heating process, and then incorporating it into EG, a composite phase change materi...
