Radiative　cooling　without　using　electricity　represents　an　ideal　green　solution　for　air-conditioning.　Despite　exciting　progress　made　so　far,　most　of　the　radiative　cooling　materials　are　vulnerable　to　outdoor　contamination,　which　leads　to　decreased　performance.　Herein,　we　fabricate　a　hierarchically　structured　PVDF/PDMS　porous　film　which　integrates　strong　sunlight　reflectance　(97%),　high　thermal-infrared　emittance　(96%)　and　robust　superhydrophobicity　(160.2°).　The　synergy　of　the　effective　solar　reflection　and　thermal-infrared　emission　enables　the　film　to　yield　a　sub-ambient　temperature　drop　of　12.3　°C　under　strong　sunlight.　More　importantly,　the　superhydrophobicity　keeps　the　film　away　from　contamination　by　self-cleaning,　maintaining　well　the　radiative　cooling　performance　for　a　long-term　outdoor　use.　Additionally,　the　as-obtained　film　shows　excellent　chemical　durability　after　exposure　to　different　pH　solutions　and　UV　light　irradiation.　This　work　provides　a　new　strategy　to　integrate　self-cleaning　with　radiative　cooling,　showing　great　potential　to　advance　energy-free　cooling　materials　toward　real-world　applications.　©　2022　Elsevier　B.V.
