Abstract Antifouling materials are highly demanded in global marine market due to increasingly aggravated marine biofouling problem and unbalanced marine ecology. Herein, poly (vinyl imidazole-co-hydroxypropyl methacrylate-co-butyl acrylate) (P(VIm-co-HPMA-co-BA)) was prepared via free radical polymerization of commercially available monomers of vinyl imidazole (VIm), hydroxypropyl methacrylate (HPMA) and butyl acrylate (BA). Then the zwitterionic terpolymer (P(VPS-co-HPMA-co-BA)) was obtained by ionicalization of P(VIm-co-HPMA-co-BA) with 1, 3-propionate lactone (1, 3-PS) in EtOH solutions. Furthermore, the membrane samples, P(VIm-co-HPMA-co-BA) and P(VPS-co-HPMA-co-BA) were prepared by tape casting method with DI water bath. Significantly, P(VPS-co-HPMA-co-BA) membranes have shown better bactericidal activity against Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) with a mean area size of 3.5 cm2. Meanwhile, the bacterial adhesion assay showed that P(VPS-co-HPMA-co-BA) membranes were found the absence of adherent bacteria, and exhibited excellent anti-adhesion property with the increase of molar ratios of PVPS by the observation of bacteria population density. The mechanical testing results indicated that the molar ratios of 65/10/25 in P(VIm-co-HPMA-co-BA) membranes and P(VPS-co-HPMA-co-BA) membranes had high breaking elongation ratio and great tensile strength. Specifically, the maximum tensile strength of P(VPS-co-HPMA-co-BA) membrane could reach up to 10.9 MPa. The results showed that the novel P(VPS-co-HPMA-co-BA) membrane exhibited both anti-bacterial, anti-adhesion property and mechanical performance, manifesting its prospectively potential applications in new highly efficient and eco-friendly marine antifouling coatings.

基于两性离子三元共聚物的涂层可能用于抗菌和防污应用

摘要 由于海洋生物污染问题日益严重和海洋生态失衡，全球海洋市场对防污材料的需求量很大。在此，聚（乙烯基咪唑-共-甲基丙烯酸羟丙酯-共-丙烯酸丁酯）（P（VIm-co-HPMA-co-BA））是通过乙烯基咪唑（VIm）、甲基丙烯酸羟丙酯的市售单体的自由基聚合制备的。 (HPMA) 和丙烯酸丁酯 (BA)。然后通过 P(VIm-co-HPMA-co-BA) 与 1, 3-丙酸酯内酯 (1, 3-PS) 的离子化获得两性离子三元共聚物 (P(VPS-co-HPMA-co-BA))乙醇溶液。此外，膜样品P(VIm-co-HPMA-co-BA)和P(VPS-co-HPMA-co-BA)通过流延法和去离子水浴制备。显着地，P(VPS-co-HPMA-co-BA) 膜对革兰氏阴性大肠杆菌（E.coli）和革兰氏阳性金黄色葡萄球菌（S. aureus）显示出更好的杀菌活性，平均面积为 3.5 cm2。同时，细菌粘附试验表明，P(VPS-co-HPMA-co-BA)膜没有粘附细菌，通过观察细菌数量，随着PVPS摩尔比的增加，P(VPS-co-HPMA-co-BA)膜表现出优异的抗粘附性能密度。力学测试结果表明，P(VIm-co-HPMA-co-BA)膜和P(VPS-co-HPMA-co-BA)膜的摩尔比为65/10/25具有较高的断裂伸长率和良好的断裂伸长率。抗拉强度。具体而言，P(VPS-co-HPMA-co-BA)膜的最大拉伸强度可达10.9 MPa。
