相变材料微胶囊的国内外研究现状

The Current International Research Situation of Micro-encapsulated Phase-change Materials

相变材料微胶囊作为一种复合材料,解决了固液相变材料相变时体积变化以及泄漏问题;提供了大的传热面积改善了传热;还可防止相变材料的性质改变。相变材料微胶囊已经广泛应用于纺织品、传热流体、建筑物、军事、农业等领域。作为近年来研究热点,详细介绍了这种新型的复合材料特点、制备方法及目前研究现状。

As a kind of compound materials, Micro- encapsulated phase- change materials （ MEPCM ） has being widely studied in recent years. It solved the problem of volume changed as well as leakage when solid-liquid phase change materials change phase. It provided greater heat transfer areas, improved heat transfer efficiency ; It prevented PCM from changing it/s nature. MEPCM has been widely applied in the filed of textile, heat transfer fluid, building, military, agriculture and so on. This article introduced characteristics, the preparation methods and the present study situation of MEPCM in detail.
