Membrane fouling is a major hindrance to the effective application of polyethersulfone (PES) membranes. Synthetic silver nanoparticles @ zeolitic imidazolate framework‐8 (AgNPs@ZIF‐8) hybrid crystals were used to modify the PES microfiltration membranes for mitigating membrane fouling and better water permeability. The surface modification of AgNPs@ZIF‐8 hybrid crystals improved the antifouling property of the membranes. The number of live bacteria in the bacteria suspension was over 90 % less than that of control membranes. Furthermore, after surface modification, the membrane permeability was enhanced, which was due to increased surface hydrophilization of the membranes which could partly explain the improved antifouling property. The results demonstrate that the use of AgNPs@ZIF‐8 hybrid crystals is a feasible and attractive approach for the development of antifouling membranes.

AgNPs @ ZIF-8杂化材料改性的聚醚砜微滤膜，具有良好的抗污垢性和渗透性

膜结垢是有效使用聚醚砜（PES）膜的主要障碍。合成的银纳米粒子@沸石咪唑酸酯骨架8（AgNPs @ ZIF-8）杂化晶体用于修饰PES微滤膜，以减轻膜污染和更好的透水性。AgNPs @ ZIF-8杂化晶体的表面改性改善了膜的防污性能。细菌悬浮液中的活细菌数量比对照膜少90％以上。此外，在表面改性后，膜的渗透性提高，这是由于膜的表面亲水性增加，这可以部分解释改善的防污性能。
