It is highly feasible to utilize phase change energy storage technology to construct a phase change material (PCM)-based thermal management system for electronic devices. In this paper, stearic acid (SA) was used as the PCM, and expanded graphite (EG) was chosen as the carrier to prepare SA/EG CPCM. The results showed that EG could prevent the melted SA from leaking, and the combination between SA and EG was only physical. When the mass fraction of EG was 11%, the SA/EG CPCM had good shape stability with a phase change temperature ( T m ) of 67...
