In this article, researchers used the sol-gel method to create a thermally conductive phase change material (PCM), paraffin/silicon dioxide (SiO2)/expanded graphite (EG) composite. This PCM is composed of a supporting material, silica gel, and a thermally conductive material, expanded graphite. Thermal properties, such as conductivity and diffusivity were determined experimentally, and a differential scanning calorimeter was used to characterize the melting temperature and latent heat of the PCM. ...
