摘　　要：相变材料(PCM)可以弥合热能供需在时间和空间上的差距,被广泛应用于热能存储和热管理系统中。然而,单一的PCM具有易泄漏、体积变化、相分离和腐蚀等缺陷,因此,通过微胶囊技术将PCM封装制备微胶囊复合相变材料(MEPCM),并通过不同纳米填料增强其性能,既可以有效克服以上缺陷,又能提高其热性能和运行稳定性。本文首先介绍了MEPCM的芯材和壳体的选择原则、MEPCM的组成及制备策略,着重阐述了不同维度纳米填料对MEPCM热性能的影响,总结了MEPCM在建筑、纺织品及热管理等领域中的应用,最后,展望了纳米填料在合理设计和构建高性能MEPCM方面的未来研究方向和挑战。Phase change materials(PCM)can bridge the gap between heat supply and demand in time and space,and are widely used in heat storage and thermal management systems.However,a single PCM has defects such as easy leakage,volume change,phase separation and corrosion.Therefore,microencapsulated PCM to prepare microencapsulated composite phase change materials(MEPCM)by microencapsulated technology and enhanced by different nano-fillers can not only effectively overcome the above defects,but also improve its thermal performance and operational stability.This paper first introduces the selection principle of the core material and shell of MEPCM,the composition and preparation strategy of MEPCM,focuses on the influence of nano-fillers of different dimensions on the thermal properties of MEPCM,and summarizes the application of MEPCM in the fields of construction,textiles and thermal management.The future research directions and challenges of nano-fillers in rational design and construction of high-performance MEPCM are also discussed.
