摘　　要：相变材料(PCM)具有很高的能量密度,并且可以在几乎恒定的温度范围内吸收和释放热量,所以利用PCM进行热能储存是提高能源利用率的有效方法。但是在广泛应用的热能储存系统中,相变材料存在泄露问题。可以利用多孔材料有效解决相变材料在固-液相变过程中的泄露问题。主要介绍了作为PCM支撑材料的多孔材料的研究进展,阐明了在新型多孔材料支撑下构建形状稳定复合PCM(ss-PCM)的设计和构建,展望了未来多孔材料在相变领域的发展及应用前景。Phase change materials(PCM)have a very high energy density and can absorb and release heat over a nearly constant temperature range.The thermal energy storage using PCM is an effective way to increase energy efficiency.However,in widely used thermal energy storage systems,phase change composites have leakage problems.Porous materials can be used to effectively solve the leakage problem of phase change materials in the solid-liquid phase transition process.The research progress of porous materials as support materials for phase-change composites was mainly introduced,and clarified the design and construction of shape-stable composite PCM(ss-PCM)under the support of new porous materials,and looked forward to the future development and application prospects of porous materials in phase transition field.
