微胶囊相变材料在建筑节能领域的研究与应用

Research and Application of Microencapsulated Phase Change Material in Energy-saving Building

如何对固-液相变材料进行有效的封装,是阻碍其规模化应用的主要难点之一。微胶囊技术以其独特的优势,近年来得到国内外专家的广泛关注。介绍了可作为芯材的相变材料及相应的壁材、两种典型的微胶囊制备工艺,重点总结了微胶囊的表征方法,同时讨论了国内外微胶囊相变材料在建筑节能领域中的应用现状、存在的问题以及发展前景。

How to package solid/liquid Phase Change Material is the key factor for its commercial application. Microencapsulating has been paid attention to all over the world recently. The micro-encapsulation technology, including the core and the shell materials, two significant synthesis processes, various characterization methods are reviewed in this paper. Its applications and recent progress in energy saving building are introduced.
