3D-Printed Phase-Change Porous Monoliths for Adaptive Radiative Cooling with High Solar Reflectance and Latent Heat Buffering

. This phase-change radiative cooling monolith enables approximately 9.0 °C subambient cooling under direct sunlight while delaying nighttime overcooling by ∼2.5 h. This study presents an efficient strategy for developing radiative cooling materials that integrate high spectral selectivity, latent heat buffering, and scalable manufacturability.
