並列摘要

This article introduces passive radiative cooling materials, electromagnetic interaction physics, and design. Materials structure is an important parameter for realizing daytime radiative cooling, and three main material structures are proposed (ie, multilayer structure, porous polymer, random distribution structure). Subsequently, various manufacturing processes and characteristics of multiple materials used for daytime radiative cooling are discussed. Finally, the challenges and development of daytime radiative cooling in the future are discribed, hoping that this article will be helpful for further research and development in this field.
