Long-term and green marine antifouling coatings are an important means to prolong the service life of ships and other marine instruments and equipment. To accomplish this, we prepared three new green and high-efficiency antifouling coatings containing phthalimide derivatives inspired by capsaicin (PDIC-AC) by using a collaborative strategy that incorporates self-polishing, fouling repelling, and antifouling properties. Static simulation tests confirmed that the zinc acrylate resin of the PDIC-AC has excellent self-polishing properties due to changes in the roughness, surface free energy, and mass loss. Antifouling tests demonstrated that both PDIC and PDIC-AC possess efficient antibacterial and anti-algal effects. Moreover, marine field tests showed that the PDIC-AC are highly antifouling for at least 9 months, and their antifouling effect is similar to that of an antifouling coating with chlorothalonil (CT-AC). The collaborative strategy in this study can be used to research and develop long-term environmentally friendly antifouling coatings.
长效环保型海洋防污涂料是延长船舶和其他海洋仪器设备使用寿命的重要手段。为此，我们受辣椒素启发，采用协同策略，通过引入含邻苯二甲酰亚胺衍生物（PDIC-AC），制备了三种具有自抛光、防污和防污性能的新型绿色高效防污涂料。静态模拟试验证实，由于粗糙度、表面自由能和质量损失的变化，PDIC-AC 的丙烯酸锌树脂具有优异的自抛光性能。防污试验表明，PDIC 和 PDIC-AC 均具有高效的抗菌和抗藻作用。此外，海洋现场试验表明，PDIC-AC 的防污性至少可达 9 个月，其防污效果与含百菌清（CT-AC）的防污涂料相似。本研究中的协同策略可用于研究和开发长效环保型防污涂料。
