Cooling represents a considerable fraction of energy consumption. However, it is indispensable to develop eco-friendly, biocompatible, and ductile cooling materials for personal applications. In this study, we demonstrate the ductile cooling ability with phase change of thermally passivated hydrogel composite materials with additive manufacturing ability. Thermal evaluation of such water-based composites indicates a superior cold retention capacity with a cooling comfort over 6 hours, while the composite displays a full recovery when strained up to 80% in uniaxial compression tests as a result of the intertwining between covalent and ionic bonds. A three-layered rectangular model was utilized to simulate the problem in a steady-state thermal analysis to study the cooling effect. Our findings indicate the potential of hydrogel as a cooling phase-change medium and its contribution towards ductile cooling applications.

球墨冷却相变材料

冷却占能源消耗的很大一部分。然而，开发用于个人应用的环保、生物相容性和延展性冷却材料是必不可少的。在这项研究中，我们展示了具有增材制造能力的热钝化水凝胶复合材料的延展冷却能力和相变。这种水基复合材料的热评估表明其具有出色的保冷能力和超过 6 小时的凉爽舒适度，而由于共价键和离子键之间的交织，复合材料在单轴压缩试验中应变高达 80% 时显示出完全恢复. 使用三层矩形模型模拟稳态热分析中的问题，以研究冷却效果。
