Abstract:

The increasingly severe issues about energy and the environment demand the development of energy-efficient and environmentally friendly cooling technologies. Radiative cooling materials and technologies with the characteristic of cooling through thermal radiation without the need for energy consumption have become a highly focused research field in recent years. Radiative cooling paints exhibit significant scientific research value and enormous engineering application prospects due to their advantages of simple preparation, low cost and convenient application. This review summarized the cooling principles and current research status of radiative cooling paint, including inorganic paint, organic paint and organic-inorganic hybrid paint. It discussed the applications of radiative cooling paint in building energy efficiency, human thermal management and aerospace. Finally, from the perspective of combining the performance of radiative cooling paint with practical applications, this article proposed that enhancing the weather resistance of radiative cooling paint and developing new applications for paint as well as dynamic cooling paint, were the future development trends. Research on radiation cooling paint was of significant importance for addressing energy issues and establishing an environmentally friendly society.
