相变材料微/纳胶囊的研制及其在红外隐身中的应用

Preparation of nanoencapsulated/microencapsulated phase change materials and it's application in infrared camouflage

相变材料微/纳胶囊是利用保护性囊壁包裹相变材料制得的微粒,它们在相变材料历经相转变时可以吸收、储存和释放大量的潜热,而本身温度基本不变。本文综述了相变材料微/纳胶囊的主要制备方法及最新研究进展,介绍了它们在红外隐身中的应用,并展望了其应用前景。

Microencapsulated/Nanoencapsulated phase change materials（Micro/NanoPCMs） are tiny particles containing PCMs surrounded by protective coating or shell.Micro/NanoPCMs can absorb,store,and release large amounts of latent heat when PCMs change phase or state,while their temperature are almost constant.The preparation of Micro/NanoPCMs and their latest progress were reviewed.In addition,the application of Micro/NanoPCMs in infrared camouflage field and their prospect were also discussed.
