High‐Entropy Chromate Metafabric for Broadband Infrared Radiative Cooling

nanofibers demonstrate excellent spectral response and flexibility, enabled by restricted planar infrared scattering and randomly distributed amorphous regions. After weaving them into a fabric-like architecture, the resulting metafabric demonstrates both ultra-high emissivity within a broad IR band, flexibility, exceptional temperature resistance, and structural stability during bending. Theoretical simulations demonstrate that the metafabric exhibits additional cooling properties and a high cooling power compared to conventional cooling systems. These advancements highlight significant potential for efficient cooling in next-generation spacecraft thermal management systems.
