中文简介
被动辐射冷却(PRC)技术是一种无需外部能源输入的绿色冷却方法,展现出在节能建筑中极具潜力的应用。然而,随着应用环境的变化,快速切换热管理性能既困难又极其重要。在这项工作中,设计了一种基于聚二乙烯苯(PDVB)纤维凝胶相变材料(PCM)的温度自适应辐射冷却涂层。它成功实现了 0.3–2.5 微米涂层反射率的智能调节,利用温度响应的辐射和相变能量储存特性的协同效应。当温度从 30°C(低于相变温度)升至 60°C(高于相变温度)时,材料的平均反射率从 53.25%升至 72.45%,而在大气透明窗口(8–13 微米)中发射率高达 95.72%。在户外测试中,涂有凝胶的钢基材在中午高温时段平均温度下降 12.3°C,相较未涂层钢材。但在夜间冷却时,它通过降低反射率并释放 PCM 潜热来抑制过度冷却,使平均温度下降限制在 0.2°C,相较于无涂层钢材。它提供了一种新的智能热管理方法。

In this work, a temperature‐adaptive radiative cooling coating based on the polydivinylbenzene (PDVB) fiber‐gelled phase change material (PCM) was designed. It successfully realizes intelligent adjustment of coating reflectivity in 0.3–2.5 µm by the synergistic
