Drawing self-cleaning technology into polymer membranes offers an extensive solution to overcome the membrane fouling obstacle. Herein, the GO-ZnO-Ag nano-hybrid particles with photocatalytic activity prepared via the microwave hydrothermal method were immobilized in poly(m-phenylene isophthalamide) (PMIA) membranes. Not only was the thorny issue in catalyst recovery avoided, but also the satisfactory photocatalytic self-cleaning performance of the polymer membrane was awarded. GO and noble metal silver nanoparticles (AgNPs) acted as a conductive electron transfer carrier and an electron host, respectively, which hindered the recombination rate of excited electrons and holes on ZnO under UV light. The UV-driven PMIA membrane photodegradation rates of MB and Cr(VI) were up to 97.2% and 94.3%, respectively, at 150 min on photodegradation kinetics. Also, MB was completely degraded at 180 min. For MB and Cr(VI) mix solutions, their degradation efficiencies were 78.1% and 71%, respectively. The BSA rejection rate of the modified polymer membrane was 93.8%, and the water flux was 408.8 (L·m⁻²·h⁻¹). Permeability was maintained at a high level after repeated use. Therefore, the newly designed PMIA/GO-ZnO-Ag series membranes could expand the application of polymers in wastewater disposal industry.

将自清洁技术引入聚合物膜中，为克服膜污染障碍提供了广泛的解决方案。在此，将通过微波水热法制备的具有光催化活性的 GO-ZnO-Ag 纳米杂化颗粒固定在聚（间苯二甲酰胺）（PMIA）膜中。不仅避免了催化剂回收的棘手问题，而且聚合物膜的光催化自清洁性能令人满意。GO和贵金属银纳米颗粒（AgNPs）分别作为导电电子转移载体和电子主体，阻碍了紫外光下ZnO上激发电子和空穴的复合率。根据光降解动力学，在 150 分钟时，紫外线驱动的 PMIA 膜对 MB 和 Cr(VI) 的光降解率分别高达 97.2% 和 94.3%。此外，MB 在 180 分钟时完全降解。对于 MB 和 Cr(VI) 混合溶液，它们的降解效率分别为 78.1% 和 71%。改性聚合物膜的BSA截留率为93.8%，水通量为408.8（L·m^-2 ·h ^-1 )。反复使用后渗透率保持在较高水平。因此，新设计的PMIA/GO-ZnO-Ag系列膜可以扩大聚合物在污水处理行业的应用。
