摘要

本文对现有辐射冷却材料的微观机理进行了综述。本文在阐明辐射冷却的基本物理概念的基础上，分析了光子晶体辐射冷却器、聚合物辐射冷却器、极性介电粒子-聚合物辐射冷却器和自适应辐射冷却器产生高效中红外发射率的微观机理。然后，详细讨论了不同材料的中红外发射率和相关冷却性能、不同辐射冷却器的优缺点及其应用场景。最后，推导了光谱调制的阈值，以解决中红外发射率与太阳反射率之间的关系，从而实现辐射冷却。本文综述可为辐射冷却器的设计和应用提供指导。

Microscopic mechanism and applications of radiative cooling materials: A comprehensive review

This paper presents a state-of-the-art review on the microscopic mechanisms of existing radiative cooling materials. In this review, we analyze the microscopic mechanisms of efficient mid-infrared emissivity generated by photonic crystal-based radiative coolers, polymer-based radiative coolers, polar dielectric particle-polymer-based radiative coolers, and adaptive radiative coolers after clarifying the basic physical concepts of radiative cooling. Then, the mid-infrared emissivity and associated cooling properties of different materials, advantages and disadvantages of different radiative coolers and their application scenarios are discussed in detail. Finally, the threshold of spectral modulation is derived to address the relationship between mid-infrared emissivity and solar reflectance to achieve radiative cooling. This review can provide guidance for the design and application of radiative coolers.
