Mussel-inspired dopamine (DA) surface modification has been widely recognized as a promoting strategy to design and exploit valuable multifunctional materials. Herein, polysulfone porous membrane was modified by the co-deposition of DA and sodium polystyrene sulfonate. In the case of extended duration of the reaction time, the water contact angle of the membrane decreased by 30 ° and the color of the modified membrane presented dark. The rejection rates of bovine serum albumin and lysozyme can close to 100% of the modified membrane and the bacteriostatic rate reached 100% at 18 h. In addition, the co-deposited membrane performed well bactericidal and excellent antiadhesion to Escherichia coli. This work provides a simple way for the fabrication of an antibacterial surface.

通过多巴胺和聚苯乙烯磺酸钠表面共沉积提高抗菌性能的聚砜膜

受贻贝启发的多巴胺 (DA) 表面改性已被广泛认为是设计和开发有价值的多功能材料的一种促进策略。在此，聚砜多孔膜通过 DA 和聚苯乙烯磺酸钠的共沉积改性。在延长反应时间的情况下，膜的水接触角降低了30°，改性膜的颜色呈现暗色。牛血清白蛋白和溶菌酶的排斥率接近改性膜的100%，18 h抑菌率达到100%。此外，共沉积膜具有良好的杀菌和对大肠杆菌的优异抗粘附性。这项工作为制造抗菌表面提供了一种简单的方法。
