Microbial-influenced corrosion and marine biofouling have become a thorny problem restricting the effective long-term operation of marine engineering. In this study, a novel antibacterial coating system for marine corrosion and fouling control was developed to integrate and improve the antibacterial performance. The coating system was composed of an epoxy primer and a low surface energy organosilicon/polyurethane topcoat, while quaternary ammonium salt (QAS) was added as an antimicrobial agent. The primer provided excellent corrosion protection. The antifouling performance was significantly improved by the combined effect of low surface energy and antibacterial agents, resulting in an extended service life and enhanced environmental sustainability of the coating system. Furthermore, the satisfactory results of the above coating system were confirmed by 8 weeks of hanging tests in the ocean, which exhibited potential application prospects in marine engineering in the future.
微生物影响的腐蚀和海洋生物污损已成为制约海洋工程长期有效运行的棘手问题。在本研究中，开发了一种用于海洋腐蚀和污损控制的新型抗菌涂层系统，以整合并提高抗菌性能。该涂层系统由环氧底漆和低表面能有机硅/聚氨酯面漆组成，同时添加了季铵盐（QAS）作为抗菌剂。底漆提供了优异的防腐蚀保护。低表面能和抗菌剂的联合作用显著提高了防污性能，延长了涂层系统的使用寿命并增强了其环境可持续性。此外，上述涂层系统在海洋中进行的8周挂片试验证实了其令人满意的效果，表明其在未来海洋工程中具有潜在的应用前景。
