Summary: | A novel composite phase change materials (PCMs) of paraffin/TiO<sub>2</sub>/active-carbon was prepared by a microemulsion method, where paraffin acted as a PCM and titanium dioxide (TiO<sub>2</sub>) as matrix material, and a small amount of active carbon was added to improve the thermal conductivity. The compositions, morphology and thermal properties of the paraffin/TiO<sub>2</sub>/active-carbon composite PCMs were characterized by XRD, SEM, TGA and DSC respectively. The shape stability during phase change process of this composite was also tested. The results show that paraffin is well encapsulated by TiO<sub>2</sub> matrix, and thus exhibiting excellent shape-stabilized phase change feature. Besides, this composite PCM also presents superhydrophobic property. Therefore, these multifunctional features will endow PCMs with important application potential in energy efficient buildings. |
