Characterization and Applications of Flexible Polymer Metasurface Passive Cooling Films

Radiative cooling technology is an emerging passive cooling technique that requires no energy consumption. This thesis focuses on practical applications, designing and manufacturing high-performance radiative cooling films that are simple in process, low in cost, suitable for mass production, and reusable, all from the perspectives of optics, and thermodynamics. Additionally, a comprehensive analysis of the heat transfer processes and the mechanisms of multiple influencing factors in radiative cooling has been conducted. This research will aid in further exploring feasible methods to enhance radiative cooling performance and promote the broader application of radiative cooling technology.
