Storage of thermal energy can be achieved by using sensible heat, latent heat of phase change materials (PCM), chemical reaction heat, and photochemistry. Among these various thermal energy technologies, the use of PCM is one of the most attractive methods for heat storage. In this study, PCM/ceramic composites were prepared by stirring and sonication of ceramics filler in erythritol at different mass fractions. The surface and structural properties of the composites were determined by scanning electron microscopy (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD). The thermal properties of the composites were studied by thermal conductivity (TC) and thermogravimetric analyzer (TGA). The latent heat and thermal cycling stability were evaluated by differential scanning calorimetry (DSC). |
