Hydrophobic　anti-wetting　membranes　have　many　applications,　such　as　oily　wastewater　treatment　via　oil/water　separation,　desalination　via　membrane　distillation,　and　carbon　capture　via　gas-liquid　membrane　contactors.　Herein,　we　used　a　simple　and　scalable　method　to　fabricate　robust　superhydrophobic　polyvinylidene　fluoride　(PVDF)　based　membranes　by　one-step　spray-coating　of　fluorinated　SiO2　nanoparticles.　The　prepared　PVDF　membrane　was　systematically　characterized　by　Fourier　transform　infrared　spectroscopy,　scanning　electron　microscopy,　X-ray　photoelectron　spectroscopy　and　contact　angle　measurements.　The　modified　PVDF　membrane　had　excellent　superhydrophobicity　with　an　extremely　high　water　contact　angle　up　to　171.8　+/-　1.1　degrees　and　a　low　sliding　angle　of　1.69　+/-　0.13　degrees,　due　to　the　fluorinated　close-packed　hydrophobic　SiO2　nanoparticles　on　the　surface.　The　modified　PVDF　membrane　maintained　its　relatively　stable　superhydrophobicity　under　various　harsh　conditions,　i.e.,　exposure　in　hot　water,　NaOH　and　HCl,　ultrasonication　and　high-speed　flushing,　indicating　the　superior　robustness　and　stability.　The　prepared　membrane　also　exhibited　consistent　separation　efficiencies　up　to　99.88　+/-　0.03%　in　water-in-oil　emulsions,　and　superior　recyclability　and　durability　over　40　cycles.　In　addition,　spray-coating　showed　its　great　promise　in　engineering　various　superhydrophobic　surfaces　on　different　substrates　and　excellent　scalability　in　fabricating　large-size　membranes.　This　study　demonstrates　a　facilely　scalable　spray-coating　method　for　engineering　robust　superhydrophobic　surfaces　and　membranes　that　can　be　potentially　used　for　various　gas,　vapor　and　water/oil　separations.
