The　dendritic　polyamido-amine/urushiol　composite　coatings　were　prepared　by　an　efficient,　controllable,　green　and　convenient　method　via　two　steps　of　electrophoresis　deposition.　Under　optimal　mass　concentration　(6.8　wt%),　the　urushiol　particles　in　the　electrophoretic　solution　remained　excellent　dispersion　state　and　uniform　size　distribution.　In　the　first-step　of　electrooxidation　polymerization　of　urushiol,　the　unsaturated　side　chains　were　successfully　crosslinked　and　deposited　on　the　surface　of　the　anode　to　form　a　coating.　In　the　second-step　of　the　electrophoresis　deposition,　polyamido-amine　dendrimers　were　crosslinked　with　urushiol　molecules　to　produce　the　urushiol　Schiff　base　compounds.　Composite　coatings　contained　compact　and　uniform　structure　and　showed　better　thermal　stability　compared　with　unmodified　urushiol　coatings.　In　addition,　the　hardness,　impact　resistance,　flexibility　and　adhesion　were　remarkably　strengthened.　Moreover,　the　medium　resistance　was　also　significantly　improved.　©　2022
