Oil　contamination　and　industrial　organic　pollutants　emission　have　been　a　serious　problem　affecting　the　ecological　and　residential　environment.　Membrane-based　separation　shows　great　application　prospect　due　to　its　low-cost,　environmental-friendly　and　easy　operation.　Therefore,　the　development　of　efficient　oil-water　separation　membranes　is　highly　desirable.　Herein,　a　fabric　filter　with　superwettability　was　prepared　by　coating　urchin-like　fluorinated　covalent　organic　frameworks　(COFs)　on　fabric,　which　was　well　utilized　in　filtering　immiscible　oil-water　mixture　and　surfactant-stabilized　water-in-oil　emulsion　driven　only　by　gravity　for　the　first　time.　The　as-prepared　COF　fabric　filter　(defined　as　fabric@u-FCOF)　possessed　many　outstanding　properties,　including　superhydrophobicity　with　the　water　contact　angle　of　approximately　151.6　degrees,　satisfactory　resistance　for　alkaline,　acidic　and　saline　environments,　as　well　as　superior　mechanical　durability　under　harsh　conditions.　Because　of　the　super-micropore　of　fabric@u-FCOF　and　the　nanopore　in　the　COF　coating,　the　obtained　fabric@u-FCOF　exhibited　excellent　performances　in　terms　of　separation　efficiency　and　permeability,　in　which　the　oil　flux　was　up　to　16964　L.m(-1).h(-2)　and　separation　efficiency　for　the　mixed　o-dichlorobenzene/water　was　higher　than　99.4%.　In　addition,　the　fabric@u-FCOF　also　showed　excellent　self-cleaning　performance　due　to　the　micro/nano　hierarchical　structure　of　its　surface.　These　excellent　properties　make　it　an　ideal　candidate　for　applications　of　oil/water　separation　and　water　purification.
