In this work, a series of novel multi-energy driven composite phase change materials (PCMs) were fabricated with paraffin wax (PW) as PCM, poly(styrene-b-ethylene-co-butylene-b-styrene) (SEBS) as the thickening agent, and reduced graphene oxide aerogel (rGOA) as multi-energy capture agent and support material. When the mass fraction of SEBS is in the range of 5 wt%-15 wt%, the composite PCMs can be formed as form-stable PCMs (FSPCMs) by the physical reaction. The enthalpy value of PW/SEBS₅/rGOA is measured as high as 226 J/g. The prepared FSPCMs show a good thermal reliability due to little reduction of enthalpy value after 200 accelerate cycles. And the prepared FSPCMs present a good thermal stability according to the thermogravimetric analysis. The thermal conductivity results show that rGOA slightly improves the thermal conductivity of the FSPCMs. Moreover, the prepared FSPCMs show excellent photo-thermal and electro-thermal conversion performance with the help of rGOA which can harvest the photons and electrons. As a result, the PW/SEBS/rGOA PCMs have great promise in areas such as solar/electrical energy collection, thermal energy storage, and thermal management.

在这项工作中，以石蜡（PW）为PCM，聚（苯乙烯-b-乙烯-共-丁烯-b-苯乙烯）（SEBS）为材料，制备了一系列新型多能驱动复合相变材料（PCM）增稠剂，还原氧化石墨烯气凝胶（rGOA）作为多能量捕获剂和支撑材料。当 SEBS 的质量分数在 5 wt%-15 wt% 范围内时，复合 PCMs 可以通过物理反应形成为形状稳定的 PCMs (FSPCMs)。PW/SEBS ₅的焓值/rGOA 测得高达 226 J/g。由于 200 次加速循环后焓值几乎没有降低，因此制备的 FSPCM 显示出良好的热可靠性。根据热重分析，制备的 FSPCMs 表现出良好的热稳定性。热导率结果表明 rGOA 略微提高了 FSPCMs 的热导率。此外，在rGOA的帮助下，制备的FSPCMs表现出优异的光热和电热转换性能，rGOA可以收集光子和电子。因此，PW/SEBS/rGOA PCM 在太阳能/电能收集、热能储存和热管理等领域具有广阔的前景。
