Ships and underwater facilities suffer from marine biofouling, which causes great harm. The most effective method against biofouling is to use self-polishing antifouling coatings. However, traditional coatings achieve antifouling performance by releasing toxic heavy metal antifouling agents, causing ecological problems. To solve this contradiction, a self-polishing antifouling coating polymer based on eugenol methacrylate was prepared. The hydrolysis of phenolic ester group realizes the transformation of resin segment from hydrophobicity to hydrophilicity. The self-polishing process releases eugenol, which is natural and non-toxic into seawater. It is the first time when self-polishing coating polymer achieves self-polishing by hydrolysis of phenolic ester groups and release of natural phenolic products. Eugenol release rate was the fastest at the beginning of immersion of the coating, reaching 0.48 μg·cm⁻²·day⁻¹ for EMFP-25. After immersion in artificial seawater for 15 days, the release rate of eugenol from the coating tends to be stable, and the EMFP-25 with the highest release rate can reach 0.14 μg·cm⁻²·day⁻¹. The resin has good antibacterial and anti-algae properties, and the mussel attachment experiments show that mussels have a tendency to avoid resin coatings with high eugenol content.

船舶和水下设施遭受海洋生物污损，危害极大。对抗生物污染最有效的方法是使用自抛光防污涂料。然而，传统涂料通过释放有毒重金属防污剂来实现防污性能，造成生态问题。为了解决这一矛盾，制备了一种基于丁香酚甲基丙烯酸酯的自抛光防污涂料聚合物。酚酯基团的水解实现了树脂链段由疏水性向亲水性的转变。自抛光过程将丁香酚释放到海水中，这是天然且无毒的。自抛光涂料聚合物首次通过酚酯基水解和释放天然酚类产品实现自抛光。^-2 ·天^-1对于 EMFP-25。在人工海水中浸泡15天后，涂层中丁香酚的释放速率趋于稳定，释放速率最高的EMFP-25可达0.14 μg·cm ^-2 ·day ^-1。该树脂具有良好的抗菌和抗藻性能，贻贝附着实验表明，贻贝有避免高丁香酚含量的树脂涂层的倾向。
