Abstract Polyethersulfone (PES)/sulfonated TiO2 (STiO2) nanoparticles (NPs) UF blended membranes were fabricated with different loadings of STiO2. The modified membranes exhibited significant improvement in surface roughness, porosity, and pore size when compared to the PES membrane. The P-STiO2 1 and P-TiO2 1 blended membranes exhibited higher water flux, approximately 102.4% and 62.6%, respectively, compared to PES. SPP-STiO2 and P-STiO2 showed lower Rir fouling resistance than the P-TiO2 blended membrane. Overall, the STiO2-blended membranes provide high hydrophilicity permeability, anti-fouling performance, and improved BSA rejection attributed to the hydrogen bonding force and more electrostatic repulsion properties of STiO2.

聚醚砜/磺化TiO 2 (PES-STiO 2 )超滤膜的制备和分离性能以减轻污染

摘要 聚醚砜 (PES)/磺化二氧化钛 (STiO2) 纳米粒子 (NPs) UF 共混膜制备了不同负载量的 STiO2。与 PES 膜相比，改性膜在表面粗糙度、孔隙率和孔径方面表现出显着改善。与 PES 相比，P-STiO2 1 和 P-TiO2 1 混合膜表现出更高的水通量，分别约为 102.4% 和 62.6%。SPP-STiO2 和 P-STiO2 显示出比 P-TiO2 混合膜更低的抗 Rir 污染性。总的来说，由于 STiO2 的氢键力和更多的静电排斥特性，STiO2 混合膜提供了高亲水性渗透性、防污性能和改进的 BSA 排斥。
