摘　　要：为了解决传统白色辐射制冷材料缺乏美学特性、应用场景受限的问题,基于溶剂蒸发相分离技术,引入光致发光材料,制备彩色被动辐射制冷多孔薄膜,并测试其太阳光反射率、中红外发射率以及户外降温性能。结果表明:黄色和粉色的辐射制冷薄膜太阳光反射率分别为80%和84%,中红外大气窗口发射率均达到98%以上;与环境温度相比,黄色和粉色辐射制冷多孔薄膜分别降低3.0℃和3.7℃;彩色光致发光辐射制冷多孔薄膜不但具有优异的辐射制冷效果同时兼具彩色美观实用性,可以扩展未来辐射制冷材料的应用范围。To address the aesthetic limitations and restricted application scenarios of traditional white radiative cooling materials,colored passive radiative cooling porous films were fabricated by incorporating photoluminescent materials through a solvent evaporation phase separation technique.The solar reflectivity,mid-infrared emissivity,and outdoor cooling performance of radiative cooling films were systematically evaluated.The results demonstrate that the yellow and pink radiative cooling films exhibit solar reflectance values of 80% and 84%,respectively,with mid-infrared atmospheric window emissivity exceeding 98%.Compared to the ambient temperature,the yellow and pink radiative cooling porous films achieve temperature reductions of 3 ℃ and 3.7 ℃,respectively.Colored photoluminescent radiative cooling porous films not only exhibit excellent radiative cooling performance but also possess aesthetic appeal and practical applicability,thereby significantly expanding the potential application scope of radiative cooling materials in the future.
