The　gradual　permeation　of　corrosive　mediums,　external　mechanical　damage,　and　ultraviolet　(UV)　radiationinduced　aging　are　critical　factors　contributing　to　the　rapid　deterioration　of　the　anticorrosive　functionality　of　polymer　coatings.　In　this　study,　a　two-dimensional　anticorrosive　enhancement　material,　fluorinated　graphene　loaded　with　zinc　oxide　nanoparticles　(FG@ZnO),　was　synthesized　via　the　heterogeneous　nucleation　growth　method.　This　material　was　then　embedded　into　a　polyurethane　coating　to　modify　the　coating　matrix,　and　a　biomimetic　lotus　leaf-like　fine　micro-nanostructure　was　fabricated　on　the　coating　surface　employing　a　templating　approach.　Through　this　internal-external　dual　modification　strategy,　an　FG@ZnO/SPU　composite　coating　with　multiple　protective　functions　was　constructed　to　offer　enduring　corrosion　protection　to　the　steel　substrate.　Experimental　findings　reveal　that　the　composite　coating　exhibits　excellent　superhydrophobicity,　with　a　water　contact　angle　as　high　as　152　degrees.　Even　after　immersion　in　a　3.5　%　NaCl　solution　for　80　days,　the　composite　coating　maintains　an　exceptionally　high　low-frequency　impedance　modulus　of　1.332　x　1010　Omega　cm2,　demonstrating　exceptional　long-term　anticorrosive　performance.　In　instances　of　coating　damage,　FG@ZnO　markedly　relieves　the　corrosion　reaction　between　the　corrosive　medium　and　the　steel　substrate　while　suppressing　galvanic　corrosion.　Furthermore,　the　composite　coating　demonstrates　effective　resistance　against　UV　radiation-induced　aging　effects.　These　exceptional　multiple　protective　properties　are　attributed　to　the　internal-external　dual　modification　effect　of　embedded　FG@ZnO　and　biomimetic　lotus　leaf　hydrophobic　modification.　This　study　provides　an　attractive　strategy　for　preparing　polymer　composite　coatings　with　multiple　protective　functions　for　enduring　corrosion　protection　of　metals.
