【摘要】 综合了近几年对无机芯相变微胶囊的报道,针对微胶囊相变材料(MCPCM)做了总结与概括,从其制备方法和应用领域进行了系统研究,并探讨了现存的问题以及需改进的方面。得到以下结论:微胶囊相变材料(MCPCM)是采用微胶囊封装技术对固-液型相变材料包覆封装的具有核壳结构的复合材料,可广泛地应用在太阳能光热储存、工业余热回收和传热流体领域。无机相变材料具有高储热密度、相变温度恒定、低成本等优点,因此无机芯微胶囊相变材料具有更好的应用空间。但目前采用的微胶囊相变材料也有其自身的缺点,如聚合物导热系数低,相变温度范围小等,有待于进一步研究。更多还原

【Abstract】 Based on the reports about inorganic phase-changed microencapsulation in recent years,the inorganic core microencapsulated phase change material(MCPCM) was summarized,the preparation methods and application fields were systematically studied,and the existing problems and places required to be improved were discussed.Following conclusions were obtained:MCPCM was a kind of core-shell structure composite material,which prepared by microencapsulation method that applied to solid-liquid phase change material.MCPCM could be wildly used in solar thermal storage,waste heat recovery,and heat transfer fluid.The inorganic phase change materials(PCMs) had the advantages of higher heat storage capacity,constant phase transition temperature,low cost and so on.Therefore,it had better application space.But MCPCM adopted at present had it own shortcomings,such as low thermal conductivity and small transition temperature range,therefore it needed further research.更多还原
