摘 要：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 antiadhesion characteristic of microorganisms. This research provides valuable information for solving the problem of microbial adhesion on metal surfaces in the marine environment.
