The evidence from many studies shows that antifoulants (CuO) and organic antifouling agents with broad-spectrum characteristics in antifouling coatings cause varying degrees of damage to the environment. Therefore, this study prepared CuO-free self-polishing antifouling coatings based on amide derivatives inspired by capsaicin (ADIC-CSAC) with green and environmentally friendly characteristics. First, the structure of ADIC and the composition of ADIC-CSAC were characterized by IR, H NMR, C NMR, HRMS, and EDX. Moreover, antibacterial, anti-algal, static raft tests and changes in the mass loss, roughness, contact angle, and surface energy were used to evaluate the antifouling and self-polishing properties of ADIC-CSAC. The test results showed that ADIC and ADIC-CSAC were successfully prepared and ADIC-CSAC possessed good antifouling and self-polishing properties. ADIC-CSAC exhibited antibacterial and anti-algal rates of over 88 and 72%, respectively, and was found to have satisfactory antifouling properties over 9 months in a real marine field. Overall, the prepared ADIC-CSAC possesses good and green antifouling and self-polishing properties, which lays a foundation for research on green antifouling coatings used for environmental protection.
许多研究的证据表明，防污剂（氧化铜）和具有广谱特性的有机防污剂在防污涂料中会对环境造成不同程度的破坏。因此，本研究以辣椒素（ADIC-CSAC）为灵感，制备了具有绿色环保特性的无氧化铜自抛光防污涂料（ADIC-CSAC）。首先，通过 IR、H NMR、C NMR、HRMS 和 EDX 对 ADIC 的结构和 ADIC-CSAC 的组成进行了表征。此外，还通过抗菌、抗藻、静态筏试验以及质量损失、粗糙度、接触角和表面能的变化来评价 ADIC-CSAC 的防污和自抛光性能。试验结果表明，成功制备了 ADIC 和 ADIC-CSAC，并且 ADIC-CSAC 具有良好的防污和自抛光性能。ADIC-CSAC 的抗菌率和抗藻率分别超过 88%和 72%，并且在真实海洋环境中超过 9 个月的时间里表现出令人满意的防污性能。总的来说，所制备的 ADIC-CSAC 具有良好的绿色防污和自抛光性能，为环保型绿色防污涂料的研究奠定了基础。
