Paraffin wax is especially promising due to their characteristics such as nontoxic, chemically inert, low cost, and tunable phase change temperature and high storage energy capacity. In order to prevent melt flowing during solid–liquid phase transition, encapsulation of PCMs with proper materials as shells is required. In this study, the graphene / paraffin composite PCM encapsulated with a TiO2 was prepared. The morphologies of the PCM were examined by the SEM and TEM. The Surface properties of the PCM were also investigated by FT-IR and XPS. Thermal properties were observed by DSC and TGA. |
