A zwitterionic nanofiber film was constructed through combining zwitterionic polymer with anodic aluminum oxide template for anti-adhering typical marine corrosive microorganisms, i.e. Pseudomonas aeruginosa, Desulfovibrio vulgaris and Chaetoceros muelleri. Results showed that the fabricated zwitterionic polymers film has fibrous nanostructure with uniform distribution and super hydrophilia. This film has wide anti-adhering properties, and it can effectively reduce the attachment of these three microorganisms by more than 99 %. Moreover, the adhesion of extracellular polymeric substances secreted from these three microorganisms are also inhibited, which is one reason for the fabricated nanofiber film with anti-adhesion characteristic of microorganisms. This research provides valuable information for solving the problem of microbial adhesion on metal surfaces in the marine environment.

通过将两性离子聚合物与阳极氧化铝模板相结合来构建两性离子纳米纤维膜，以抗粘着典型的海洋腐蚀性微生物，如铜绿假单胞菌，寻常型脱硫弧菌和多毛Chaetoceros muelleri。结果表明，所制备的两性离子聚合物薄膜具有均匀分布的纤维纳米结构和超亲水性。该膜具有广泛的抗粘附性能，可以有效地将这三种微生物的附着减少99％以上。此外，还抑制了由这三种微生物分泌的细胞外聚合物的粘附，这是制备具有微生物抗粘附特性的纳米纤维膜的原因之一。这项研究为解决海洋环境中金属表面上的微生物粘附问题提供了有价值的信息。
