The eco-friendly functionalized TiO₂/polymer antifouling (AF) coating was successfully synthesized by dispersing TiO₂ nanoparticles in waterborne epoxy-modified tung oil resin. The AF effectiveness of coating was evaluated toward Staphylococcus aureus (S. aureus, ATCC6538), Escherichia coli (E. coli, ATCC8739) and diatom (Cyclotella sp., FACHB-1635). The nanoTiO₂/polymer AF coating showed good antimicrobial activity both under the light and dark conditions by comparison with the pristine TiO₂ nanoparticles and bulk polymer. Under light irradiation for 50 min, the AF coating showed only 8.4% and 8% survival rate for S. aureus and E. coli. In addition, The AF coatings exhibited favorable inhibition efficacy toward the growth and adhesion of Cyclotella sp., and the efficacy was enhanced with the increase of TiO₂ content. It can be concluded that TiO₂ nanoparticles endow the AF coatings with promoted fouling resistance properties.

通过将TiO ₂纳米颗粒分散在水性环氧改性的桐油树脂中，成功合成了环保型功能化TiO ₂ /聚合物防污（AF）涂料。评价了涂层对金黄色葡萄球菌（金黄色葡萄球菌，ATCC6538），大肠杆菌（E.coli，ATCC8739）和硅藻（Cyclotella sp。，FACHB-1635）的AF效果。与原始TiO ₂相比，nanoTiO ₂ /聚合物AF涂层在明暗条件下均表现出良好的抗菌活性纳米粒子和本体聚合物。在光照射下50分钟，AF涂层对金黄色葡萄球菌和大肠杆菌的存活率仅为8.4％和8％。此外，AF涂层对Cyclotella sp。的生长和粘附表现出良好的抑制作用。，随着TiO ₂含量的增加，药效增强。可以得出结论，TiO ₂纳米颗粒使AF涂层具有增强的抗结垢性能。
