Zwitterion-Grafted 2D MXene (Ti₃C₂T_<i>X</i>) Nanocomposite Membranes with Improved Water Permeability and Self-Cleaning Properties

The development of chemically and mechanically stable nanocomposite membranes with high permeability self-cleaning properties is important for various wastewater treatment applications. Two-dimensional MXene (Ti3C2Tx) nanomaterials have attracted increasing research interest in applications, including membrane-based separation technologies treatment. Zwitterion functionalization has been widely used the surface modification hydrophilic materials to improve anti-fouling capability. In this research, an functionalized a zwitterion was prepared as nanofiller highly permeable properties. composite membrane by incorporating zwitterion-grafted (Z-MXene) into polyethersulfone (PES) via non-solvent-induced phase process. incorporation Z-MXene particles PES improved porosity, mean pore radius, hydrophilicity, tensile strength hybrid membranes. flux developed PES/Z-MXene nearly 3.1 times higher than that pristine membrane. rejection rates three representative species natural organic matter raw water (bovine serum albumin, humic acid, sodium alginate) were more 93%. abundant functional groups negative charge on also dye (∼275 ∼400% enhancement Congo red methylene blue dyes, respectively) while maintaining flux. Furthermore, exhibited best recovery ratio, reversible fouling low irreversible indicating its addition, significant chemical stability, demonstrated corrosion resistance during long-term 2 M HCl oxidant (NaOCl) solutions. This study provides high-performance
