单层鲜艳色彩辐射冷却涂料,采用超高近红外反射率
Single-Layer Vivid-Colored Radiative Cooling Paint Enabled by Ultrahigh NIR Reflectance
中文简介
辐射冷却是一种新兴的热管理技术,通过反射太阳辐射并通过大气透明窗(ATW)释放热量来冷却物体。近期辐射冷却研究强调基于涂层或涂料的设计以求实用性。然而,大多数现有涂层仅限于白色或金属色,限制了它们在需要鲜艳色彩的应用。因此,彩色辐射冷却(CRC)涂层极具价值,但许多报道的设计依赖复杂的多层结构,或在着色时性能下降。本研究报道了一种单层彩色辐射冷却(SCRC)涂料,能够实现浓烈的着色和高冷却效率。SCRC 涂料采用宽带隙六方氮化硼(h-BN)颗粒和混合色颜料,分散在聚氨酯(PU)结合剂中。红、黄、蓝、白的 SCRC 涂料实现,尽管颜色较深,红、黄、白的近红外反射率为 97%,蓝色则为 90%。与类似颜色的商业涂料相比,观察到显著降温,红、黄、白的温度下降超过 6°C,蓝色的降低超过 4°C。这些发现表明,SCRC 涂料独特地融合了鲜艳的色彩、结构简洁和坚固的冷却性能,为现实应用提供了实用路径。
英文摘要(原文)
restricted to white or metallic colors, limiting their use where vivid colors are desired. Colored radiative cooling (CRC) coating is therefore highly valuable, yet many reported designs rely on complex multilayer structures or suffer from performance loss upon coloration. In this study, a single-layer colored radiative cooling (SCRC) paint that achieves intense coloration and high cooling efficiency is reported
