Innovative film combines cooling efficiency with vibrant structural colors

In a study published in Matter, Song Yanlin's lab from the Institute of Chemistry of the Chinese Academy of Sciences (CAS) and Li Mingzhu's lab from the Technical Institute of Physics and Chemistry of CAS designed a structurally colored radiative cooling film with a hierarchically porous nested structure (SC-RC film), which can preserve highly efficient subambient cooling performance and provide an appealing colorful appearance.
