摘　　要：相变材料是目前热门的功能材料,在储存和释放能量的过程中,温度保持不变或稳定在一定的温度区间内,使得相变材料不仅能实现热量储存且具有温度调控功能。复合相变材料由于具有多种单一材料的性质而成为研究热点,并广泛应用在建筑节能、电子器件热管理等方面。本文分类归纳了相变材料的特征,并根据化学成分不同将复合相变蓄热材料分为有机-有机、无机-无机和有机-无机三大类,结合研究现状分类梳理了不同类型复合相变蓄热材料的优缺点,并对其蓄热特性进行归纳对比。总结了复合相变蓄热材料的应用现状,结合能源应用现状和环境情况进一步分析了今后的研究和发展方向,认为未来的复合相变材料应该是高效蓄热、灵敏准确、价格低廉、环保可降解的新型复合相变材料。A phase change material is a popular functional material,and owing to its high heat storage density,maintains a constant temperature during the process of storing and releasing energy,or is stable within a certain temperature range,which makes the material be able to not only realize energy storage but also achieve temperature control functionality. Composite phase change materials have become a popular research area because of their variety of single material properties,and are widely used in building-energy conservation,the thermal management of electronic devices,and cold chain transport. Its application is quite extensive when the energy supply is not continuous. This paper divides composite phase change materials according to their chemical composition into organic-organic,inorganic-inorganic,and organic-inorganic materials,determines the advantages and disadvantages of different types of composite phase change materials based on the research in recent years,and summarizes their energy storage characteristics. The present applications of composite phase change materials are summarized,and the development of research in this area is further analyzed based on the current energy use and environmental conditions. The research objectives and directions of phase-change thermal storage are illustrated,and it is concluded that future composite phase change materials should be highly efficient,accurate,cheap,environmentally friendly,and biodegradable.
