Passive radiative cooling using nanophotonic structures is limited by its high cost and poor compatibility with existing end uses, whereas polymeric photonic alternatives lack weather resistance effective solar reflection. We developed a cellular ceramic that can achieve highly efficient light scattering near-perfect reflectivity of 99.6%. These qualities, coupled thermal emissivity, allow the to provide continuous subambient in an outdoor setting power >130 watts per square meter at noon,...
The development of scalable and passive coatings that can adapt to seasonal temperature changes while maintaining superhydrophobic self-cleaning functions is crucial for their practical applications. However, the incorporation cooling heating with conflicting optical properties in a coating still challenging. Herein, an all-in-one inspired by hierarchical structure lotus leaf combines surface wettability, structure, self-adaptation obtained through simple one-step phase separation process....
Passive daytime radiative cooling that could provide sub-ambient emerges as a promising technology to reduce household energy consumption. Nonetheless, prevailing studies are predominantly focused on surface cooling, often overlooking its adaptability enclosed spaces with active technologies. Here we present multilayer film (
Abstract Achieving year‐round energy savings in buildings holds great significance toward reaching carbon neutrality and sustainability. Switchable thermal‐management materials offer an energy‐free solution to dynamically regulating internal building temperatures, by passively emitting heat into cold outer space summer, absorbing from hot sunlight winter. In addition dynamic thermal regulation, color display is another pursuit for addressing aesthetic considerations; however, most current...
Abstract Ice and frost buildup continuously pose significant challenges to multiple fields. As a promising de-icing/defrosting alternative, designing photothermal coatings that leverage on the abundant sunlight source earth facilitate ice/frost melting has attracted tremendous attention recently. However, previous designs suffered from either localized surface heating owing limited thermal conductivity or unsatisfied meltwater removal rate due strong water/substrate interaction. Herein, we...
