多孔基定型相变材料的研究进展

Review of porous materials as supporting materials for phase change materials

硅藻土、膨胀珍珠岩、膨胀石墨和高岭土等多孔材料能通过毛细管和表面张力的作用将相变材料定型,并为相变材料提供机械强度以阻止其在相变过程中发生泄漏.文章对多孔基定型相变材料的发展现状及其在建筑节能上的应用进行了综述,并对其今后在建筑节能上的应用研究及发展趋势进行了展望.

The various porous materials such as diatomite, expanded perlite, expanded graphite, kaolin, etc.were used as supports for form-stable phase change materials along with their worldwide availability. The supporting materials through capillary and surface tension forces not only provided a good mechanical strength to the whole composites, but also prevented the leakage of solid-liquid phase change materials during phase change process.This paper covers the progress research of porous materials as supporting materials for phase change materials, and the practical applications in building energy conservation were described .Meanwhile the prospect for its future deverlopment trends on energy efficiency in buildings was given.
