Corrosion　and　biofouling　are　two　common　unsolved　problems　in　the　marine　industry,　urging　the　need　of　innovative　solutions　to　tackle　both　problems　simultaneously.　Herein,　the　fabrication　of　multifunctional　microcapsules　containing　8-hydroxyquinoline　(8-HQ)　as　the　corrosion　inhibitors　and　clove　oil　as　the　natural　antimicrobial　compound　is　described　to　resolve　both　corrosion　and　biofouling　problems　simultaneously.　Microcapsules　containing　8-HQ　and　clove　oil,　featuring　good　mechanical　properties,　anticorrosion,　and　antibacterial　properties,　were　successfully　synthesized　through　in-situ　polymerization　of　melamine-formaldehyde　polymer.　The　fabricated　microcapsules　show　antibacterial　properties　against　Escherichia　coli,　Vibrio　coralliilyticus　and　E.　aestuarii,　as　revealed　from　the　standard　ASTM　E2315　time-kill　test.　Multifunctional　coatings　with　both　antibacterial　and　anticorrosion　features　were　fabricated　by　incorporating　the　fabricated　microcapsules　both　onto　and　into　the　epoxy　coatings.　According　to　the　zone　inhibition　test,　the　microcapsules-based　multifunctional　coating　possesses　antibacterial　properties　against　the　seawater　bacteria.　Manually　scratched　microcapsules-based　multifunctional　coatings　possess　anticorrosion　properties,　due　to　the　formation　of　corrosion　inhibition　layer　resulted　from　the　reaction　between　the　released　8-HQ　compound　and　the　mild　steel　substrate.　Additionally,　after　30　days　of　immersion　in　the　salt　water,　the　microcapsules-based　coatings　still　possess　anticorrosion　properties　by　forming　corrosion　inhibition　layer　at　the　scratched　region.
