Abstract

Highlights

An all-in-one photonic hydrogel was designed for above-ambient heat dissipation and flame retardancy by sky radiative cooling and evaporation cooling.
Radiative coupled with evaporation cooling can greatly improve the heat dissipation performance, indicating a 12.0 °C lower than the radiative cooling film under the same conditions.
Radiative cooling-assisted adsorption can improve atmospheric water harvesting to ensure evaporation under periodic workload and meteorological parameters.

辐射耦合蒸发冷却水凝胶，用于环境以上的散热和阻燃

通过天空辐射冷却和蒸发冷却，设计了一种一体化的光子水凝胶，用于环境上方散热和阻燃。辐射耦合蒸发冷却可以大大提高散热性能，在相同条件下比辐射冷却膜低12.0℃。辐射冷却辅助吸附可以改善大气集水，以确保在周期性负荷和气象参数下的蒸发。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
