Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.
