High-performance radiative cooling film with excellent thermostability and mechanical property realized by self-assembled nanoparticles
中文简介
辐射冷却作为一种新型的零能耗冷却技术，在冷却高度集成、小型化和柔性电子设备方面具有广阔的前景。然而，将柔性辐射冷却膜的出色冷却性能与优异的热稳定性和机械性能结合起来是一个挑战。在此，展示了一种通过可控自组装 SiO2 纳米颗粒制造高性能 SiO2 掺杂无色聚酰亚胺 (CPI)/Ag 柔性薄膜以实现高效辐射冷却的新策略。该薄膜具有高太阳光反射率（96.58%，0.4–2.5 μm）和中红外发射率（91.24%，5–20 μm）。在阳光直射下，最高冷却温度比环境温度低 7 °C，比裸铝器件低 10 °C。更重要的是，热稳定性（T∼331°C）和拉伸强度（78MPa）拓宽了其适用性。均匀分布的微小自组装纳米颗粒与基体之间的强界面相互作用对于增强辐射冷却性能、热稳定性和机械性能起着至关重要的作用。这项工作为实现电子设备的高效辐射冷却提供了有效的策略。
