Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

Advanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐
