Designer SiO<sub>2</sub> Metasurfaces for Efficient Passive Radiative Cooling
Summary
This review examines how engineered silica surfaces can be designed for passive radiative cooling, which allows buildings to cool without using electricity. While not directly about microplastics, the technology is relevant because it addresses energy efficiency and reducing environmental pollution from cooling systems. The research evaluates different design strategies for making silica-based cooling materials that could be manufactured at scale.
Abstract In recent years, an increasing number of passive radiative cooling materials are proposed in the literature, with several examples relying on the use of silica (SiO 2 ) due to its unique stability, non‐toxicity, and availability. Nonetheless, due to its bulk phonon‐polariton band, SiO 2 presents a marked reflection peak within the atmospheric transparency window (8‐13 µm), leading to an emissivity decrease that poses a challenge to fulfilling the criteria for sub‐ambient passive radiative cooling. Thus, the latest developments in this field are devoted to the design of engineered SiO 2 photonic structures, to increase the cooling potential of bulk SiO 2 radiative coolers. This review seeks to identify the most effective photonic design and fabrication strategies for SiO 2 radiative emitters by evaluating their cooling efficacy, as well as their scalability, providing an in‐depth analysis of the fundamental principles, structural models, and results (both numerical and experimental) of various types of SiO 2 radiative coolers.
