The　frequent　occurrence　of　oil　spills　not　only　results　in　the　waste　of　petroleum　resources,　but　also　poses　a　serious　threat　to　the　marine　ecological　environment.　Considering　the　large　amount　of　crude　oils　with　high　viscosity,　it　is　urgent　to　develop　a　sorbent　capable　of　efficiently　reducing　the　viscosity　for　the　cleanup　of　oil　spills.　Inspired　by　the　“lotus　effect”　and　“poikilotherm　which　utilize　the　solar　energy　for　thermoregulation”,　the　low　surface　energy　material　polydimethylsiloxane　(PDMS)　and　polypyrrole　(PPy)　were　loaded　over　the　island　nonwoven　fabric　to　fabricate　a　novel　crude　oil　sorbent　material.　The　nonwoven　fabric　achieved　an　efficient　photothermal　conversion.　Wherein,　the　fluorine-free　PDMS　was　used　to　hydrophobically　modify　the　nonwoven　fabric,　endowing　it　with　excellent　oil-water　separation　performance,　with　a　separation　efficiency　of　up　to　95%.　After　10　cycles,　the　separation　efficiency　of　PPy/PDMS　modified　nonwoven　fabric　(PPy/PDMS@NF)　was　still　above　90%,　demonstrating　superior　recyclability.　In　addition,　the　PPy/PDMS@NF　possessed　the　self-cleaning　capabilities.　Under　light　conditions,　the　PPy/PDMS@NF　was　rapidly　heated　up,　reducing　the　viscosity　of　crude　oil　and　enabling　the　effective　recovery　of　oil　spills.　Under　one　sun　illumination　(1.0　kW·m–2),　the　surface　temperature　of　the　PPy/PDMS@NF　reached　60.7　°C,　and　its　sorption　capacity　for　high-viscosity　crude　oil　reached　7　gcrude　oil·gsorbent–1.　Thanks　to　its　environmental　friendliness　and　excellent　sorption　capacity,　this　work　provides　a　new　option　for　dealing　with　the　high-viscosity　marine　oil　spills.　©　2024　SIOC,　CAS,　Shanghai,　&　WILEY-VCH　GmbH.
