摘要
定形相变材料是解决固-液相变材料在使用过程中液体泄漏问题的有效途径之一,随着柔性设备控温技术的快速发展,具备一定柔软度和柔韧性,可伸缩、弯曲、扭转变形而不失去其性能的柔性定形相变材料应运而生。热塑性弹性体因其低成本和强相容性常被用作制备柔性定形相变材料的定形基体。综述了以氢化苯乙烯-丁二烯-苯乙烯(SEBS)和烯烃嵌段共聚物(OBC)等热塑性弹性体为基体的柔性定形相变材料在材料选择、制备工艺、相变性能和柔性性能等方面的最新研究成果,并总结柔性定形相变材料在电子器件热管理与温控热疗/冷疗等领域的应用。最后,对未来柔性定形相变材料发展的研究重点和发展方向进行了展望。
Form-stable phase change materials(FSPCMs) are one of the effective ways to solve the problem of liquid leakage during the use of solid-liquid phase change materials.However,with the rapid development of flexible equipment temperature control technology,flexible FSPCMs have come into being.It has a certain degree of softness and flexibility,and can stretch,bend,twist,and deform without losing its properties.Thermoplastic elastomers can be the preferred shaped substrate for flexible FSPCMs due to their low cost and strong compatibility.In terms of material selection,preparation process,phase change properties,flexibility properties,this paper reviews the latest research results on flexible FSPCMs using thermoplastic elastomers such as styrene ethylene butylene styrene(SEBS) and olefin block copolymer(OBC) as the shaped matrix.Meanwhile,the application in the field of thermal management and thermotherapy of electronic devices is summarized.Finally,the research focus and direction of the future development of flexible FSPCMs materials are prospected.
