“In situ polymerization-blending” has been proved as an available approach to introduce capsaicin derivative containing two carbon–carbon double into membranes to enhance anti-fouling ability. However, conventional heating (CH) technique is expensive and time-consuming. In this work, a facile microwave assistance (MWA) approach was proposed for in-situ polymerization of antifouling polysulfone (PSf)/polyethersulfone (PES) and N-(5-methyl acrylamide-2,3,4 hydroxy benzyl) acrylamide (AMTHBA) composite membranes (PSf/PES-AMTHBA membranes) via phase-inversion process. This novel capsaicin derivative AMTHBA contains carbon–carbon double bonds enabled the self-polymerization process, moreover, it is also rich in hydroxyl radicals (–OH) that significantly improves the surface hydrophilicity. The resulting membrane exhibited the best performance in terms of water flux (up to 586.8 LMH) and rejection (98.5%), breaking the trade-off effect. In addition, PSf/PES-AMTHBA membranes also exhibited an outstanding antimicrobial activity with high efficiency (>85%) and excellent resistance to bacteria (E. coli). The present approach would be time-saving and high-efficiently, encouraging its wider application in efficient water purification.

已经证明“原位聚合共混”是一种将包含两个碳-碳双键的辣椒素衍生物引入膜中以增强防污能力的可用方法。然而，常规的加热（CH）技术是昂贵且费时的。在这项工作中，一个浅显的微波辅助（MWA）的做法提出了原位通过相转化法将防污聚砜（PSf）/聚醚砜（PES）和N-（5-甲基丙烯酰胺-2,3,4羟基苄基）丙烯酰胺（AMTHBA）复合膜（PSf / PES-AMTHBA膜）聚合。这种新颖的辣椒素衍生物AMTHBA包含能够实现自聚合过程的碳-碳双键，此外，它还富含羟基（-OH），可显着改善表面亲水性。所得膜在水通量（最高586.8 LMH）和拒水率（98.5％）方面表现出最佳性能，打破了权衡效果。此外，PSf / PES-AMTHBA膜还具有出色的抗菌活性，效率高（> 85％），并且对细菌（大肠杆菌）具有出色的抗性。）。本方法将节省时间并且高效，从而鼓励其在有效的水净化中更广泛的应用。
