摘要

辐射冷却材料在没有外部电源输入的情况下，在降低能源消耗方面显示出巨大的前景。然而，在可扩展和灵活的形式中集成高太阳反射率，机械稳健性和环境稳定性仍然是难以捉摸的。此次预览重点介绍了一种可工业化的微三明治结构膜（MAMS），该膜实现了创纪录的99.1%的太阳反射率和强大的中红外发射率，同时具有出色的拉伸和撕裂强度。关键在于通过双轴拉伸形成的椭球状孔隙结构，提高了光散射效率和结构完整性。这项工作克服了被动辐射冷却的关键限制，并强调了将光学设计与耐用性和大规模生产集成到现实世界部署的未来方向。

Biaxial stretching unlocks durable, high-performance radiative cooling

Radiative cooling materials have shown great promise in reducing energy consumption without external power input. Yet the integration of high solar reflectivity, mechanical robustness, and environmental stability in a scalable and flexible form remains elusive. This preview highlights an industrializable micro-sandwich-structured membrane (MAMS) that achieves a record-high solar reflectivity of 99.1% and strong mid-infrared emissivity, while offering excellent tensile and tear strength. The key lies in ellipsoidal pore architectures formed via biaxial stretching, which boost light scattering efficiency and structural integrity. This work overcomes key limitations in passive radiative cooling and highlights future directions for integrating optical design with durability and mass production toward real-world deployment.
