The　fabrication　of　micro/nano　hierarchical　structures　is　a　crucial　step　in　imparting　super-wettability　to　materials.　However,　existing　methods　often　suffer　from　drawbacks　such　as　low　efficiency,　complex　processes,　and　limited　applicability.　In　this　study,　a　simple　one-step　deposition　process　was　employed　to　prepare　a　coral-like　coating　with　a　micro/nano　hierarchical　structure.　This　was　achieved　through　the　precipitation　copolymerization　of　a　renewable　biomaterial,　urushiol,　with　1,6-hexamethylenediamine　(HDA)　in　an　ethanol　solution.　The　reaction　mechanism　of　the　precipitation　copolymerization　and　the　formation　of　the　deposited　coating　were　investigated　using　chemical　structure　and　surface　morphology　characterization.　The　study　also　examined　the　effects　of　various　reaction　conditions,　including　reactant　ratios　and　solution　pH,　on　coating　morphology　and　hydrophobicity.　Due　to　the　unique　functional　groups　and　microstructures,　the　urushiol-HDA　deposition　modification　imparted　high　hydrophobicity　to　various　substrates　without　using　low-surface-energy　modifiers,　demonstrating　its　broad　applicability.　Furthermore,　secondary　modifications　of　the　deposited　coating　endowed　the　substrates　with　more　diverse　chemical　structures　and　surface　properties.　Thus,　the　ease　of　preparation,　broad　applicability,　and　tunable　modification　effects　make　the　urushiol-HDA　deposition　modification　a　promising　method　for　creating　super-wetting　surfaces.　©　2024　Elsevier　B.V.
