This grant supports research that will contribute new knowledge related to large-scale manufacturing of radiative cooling paints, promoting both the progress of science and advancing national prosperity and sustainability. Radiative cooling is a strategy to provide electricity-free cooling by fully reflecting sunlight and effectively emitting heat to the cold sky: a net cooling effect can be realized without using any electricity. It has the potential to reduce electricity consumption and CO2 generation for air conditioning in buildings and vehicles. Conventional approaches for manufacturing radiative cooling coatings demand complex and high-cost thin-film deposition processes, which hinder large-scale applications. This award supports fundamental research to provide needed knowledge for the development of a room temperature solution-based technique to produce radiative cooling porous polymer paints. The new process will enable fast, large-scale, and low-cost manufacturing of polymeric radiative cooling paints without using organic solvents. The paints will have potential applications in building, automotive, food, chemical, and pharmaceutical industries, which benefits the US economy and society. This research involves several disciplines including manufacturing, optics, polymer science, and material science. The multi-disciplinary approach will help broaden participation of underrepresented groups in research and positively impact engineering education.Radiative cooling can alleviate several disadvantages in existing cooling techniques, such as high consumption of electricity, and usage of ozone-depleting and greenhouse gases. The research team will conduct fundamental studies to bridge the knowledge gap between scientific concept of radiative cooling and scalable manufacturing of high-performance and low-cost cooling coatings. Specifically, the team will: 1) conduct full-wave simulations to understand the interactions between solar and thermal radiations and porous polymeric materials; 2) develop scalable solution-based manufacturing methods to produce porous polymer radiative cooling neutral-colored and colorful paints, understanding effects of various parameters, such as solution concentration, vapor pressure, and temperature, on the morphology and performance of the porous paints; and 3) conduct field tests to quantify the radiative cooling capabilities of the paints under various environmental and meteorological conditions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项赠款支持将有助于与辐射冷却油漆大规模制造有关的新知识的研究，从而促进科学进步并促进国家繁荣和可持续性。辐射冷却是一种通过完全反射阳光并有效地向寒冷的天空散发热量来提供无电冷却的策略：可以在不使用任何电力的情况下实现净冷却效果。它有可能减少建筑物和车辆空调的电力消耗和二氧化碳的产生。制造辐射冷却涂层的常规方法需要复杂和高成本的薄膜沉积过程，这阻碍了大规模应用。该奖项支持基本研究，以提供基于室温溶液的技术来生产辐射冷却多孔聚合物涂料的所需知识。新工艺将使聚合物辐射冷却涂料的快速，大规模和低成本制造，而无需使用有机溶剂。这些油漆将在建筑，汽车，食品，化学和制药行业中有潜在的应用，这使美国经济和社会受益。这项研究涉及几个学科，包括制造，光学，聚合物科学和材料科学。多学科的方法将有助于扩大代表性不足的群体在研究中的参与，并对工程教育产生积极影响。放射冷却可以减轻现有的冷却技术中的几种缺点，例如高消耗电力，以及使用臭氧动力和温室气体的使用。研究小组将进行基本研究，以弥合辐射冷却的科学概念与高性能和低成本冷却涂层的可扩展制造之间的知识差距。具体而言，团队将：1）进行全波模拟，以了解太阳能和热辐射与多孔聚合物材料之间的相互作用； 2）开发基于溶液的制造方法，以产生多孔聚合物辐射冷却中性颜色和彩色涂料，了解各种参数的影响，例如溶液浓度，蒸气压和温度，对多孔油漆的形态和性能； 3）进行现场测试，以在各种环境和气象条件下量化油漆的辐射冷却能力。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估审查标准来通过评估来获得支持的。
