Abstract

In this work, the influence of molecular parameters of styrene-b-(ethylene--butylene)-b-styrene (SEBS) triblock copolymer as matrix material in form-stable phase change material (FSPCM) on the thermo-mechanical properties and leakage behavior are studied. Various SEBS grades differing in their molecular weight, styrene content, and ethylene/butylene ratio are used as supporting matrix in composites with 90 wt.% paraffin. Thermo-mechanical properties are determined by rheological measurements. The results show phase transitions temperatures from solid to hard gel, hard gel to soft gel, and soft gel to gel fluid. Paraffin leakage in FSPCM is analyzed by mass loss over time in an oven at 60 °C. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) are applied to determine the thermal energy storage capacity. Finally, the molecular weight and the styrene content are combined to the molecular weight of styrene block which is identified as the authoritative parameter for the thermo-mechanical properties of the SEBS/PCM composite.

摘要

在这项工作中，研究了作为形状稳定相变材料（FSPCM）基体材料的苯乙烯 - b -（乙烯 - 丁烯）- b - 苯乙烯（SEBS）三嵌段共聚物的分子参数对热机械性能和泄漏行为的影响。使用分子量、苯乙烯含量和乙烯/丁烯比不同的各种SEBS牌号作为含90 wt.%石蜡的复合材料的支撑基体。通过流变测量确定热机械性能。结果显示了从固体到硬凝胶、硬凝胶到软凝胶以及软凝胶到凝胶流体的相变温度。通过在60°C烘箱中随时间的质量损失分析FSPCM中的石蜡泄漏。应用差示扫描量热法（DSC）和热重分析（TGA）来确定热能存储容量。最后，将分子量和苯乙烯含量合并为苯乙烯嵌段的分子量，其被确定为SEBS/PCM复合材料热机械性能的权威参数。
