摘要 以石蜡作为相变物质、二氧化钛(TiO2)作为基体材料,添加少量活性炭提高其热导率,通过微乳液法制备出新型石蜡/TiO2/活性炭复合相变材料。利用XRD,SEM,TGA,DSC对材料的组成、形貌和性质分别进行表征,并对材料相变过程中的形状稳定性进行测试。结果表明:石蜡被TiO2有效封装,保证了材料的定形相变特征;此外该复合材料还表现出超疏水性质。这些多功能特性将使其作为多功能涂料或其他添加剂在节能建筑中具有重要的应用价值。

Abstract:A novel composite phase change materials (PCMs) of paraffin/TiO2/active-carbon was prepared by a microemulsion method, where paraffin acted as a PCM and titanium dioxide (TiO2) 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/TiO2/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 TiO2 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.
