As　an　effective　way　to　obtain　freshwater　resources,　atmospheric　water　harvesting　(AWH)　technology　has　been　a　wide　concern　of　researchers.　Therefore,　hydrogels　gradually　become　key　materials　for　atmospheric　water　harvesters　due　to　their　high　specific　surface　area　and　three-dimensional　porous　structure.　Here,　we　construct　a　core-shell　hydrogel-based　atmospheric　water　harvesting　material　consisting　of　a　shell　sodium　polyacrylate　(PAAS)　hydrogel　with　an　open　pore　structure　and　a　core　thermosensitive　poly　N-isopropylacrylamide　(PNIPAAm)　hydrogel　with　a　large　pore　size.　Theoretically,　the　mutual　synergistic　hygroscopic　effect　between　the　core　layer　and　the　shell　layer　accelerates　the　capture,　transport,　and　storage　of　moisture　to　achieve　continuous　and　high-capacity　moisture　adsorption.　Simultaneously,　the　integration　of　polydopamine　(PDA)　with　the　hydrogel　realizes　solar-driven　photothermal　evaporation.　Therefore,　the　prepared　core-shell　hydrogel　material　possesses　great　advantages　in　water　adsorption　capacity　and　water　desorption　capacity　with　an　adsorption　of　2.76　g　g-1　(90%　RH)　and　a　desorption　of　1.42　kg　m-2　h-1.　Additionally,　the　core-shell　structure　hydrogel　collects　1.31　g　g-1　day-1　of　fresh　water　in　outdoor　experiments,　which　verifies　that　this　core-shell　hydrogel　with　integrated　photothermal　properties　can　capture　moisture　in　a　wide　range　of　humidity　without　any　external　energy　consumption,　can　further　sustainably　obtain　fresh　water　in　remote　water-shortage　areas.
