Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control
Advanced Materials, EarlyView.Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.
