摘要
微胶囊相变材料是将微胶囊技术应用于相变材料而形成的新型复合相变材料,其直径为2-1000μm,它能够在10-80°C温度范围内,吸收或放出100-200 J/g的热量,而且在吸、放热量的过程中,温度几乎不发生变化。就微胶囊相变材料的特性、结构组成、制备方法和应用领域分别进行了综述。
Microencapsulated phase change materials （MCPCMs）, new kinds of composite phase change materials, were prepared with microencapsulation technology. MCPCMs is a sort of microsphere which has a diameter of 2 - 1 000 microns, and can absorb or release heat of 100 - 200 J/g in the temperature interval of 10 - 80℃. Throughout the heat absorbing of releasing process, the temperature of the MCPCMs as well as the surrounding substrate remains constant. In this paper, the characteristics, composition, preparation methods and applied fields of MCPCMs were reviewed, respectively.
