CuO/PES composite membranes were fabricated through phase inversion method, focusing on fouling reduction and improving separation performance. Copper oxide nanoparticles were used as filler additive in the membrane structure. The effect of the embedded CuO nanoparticles on the morphology was studied by considering SEM, SOM and 3D surface images. Flux recovery ratio (FRR%), water contact angle, water content, mechanical tensile strength, porosity and mean pore size, salt rejection and water flux were investigated to evaluate the performance of fabricated membranes. The SOM images showed a uniform surface for the modified membranes. SEM images showed a finger-like structure for the modified membranes. Results also denoted an increment in porosity and mean pore size of membrane at low concentration of CuO NPs, whereas the opposite trend was found at higher concentration of nanoparticles. Utilizing CuO NPs enhanced the membrane tensile strength obviously PWF significantly was improved by applying CuO NPs in membrane matrix. Highest PWF (42.63 L/m 2 h) was observed for PES-0.05wt% CuO blended membrane, whereas it was 10.41 (L/ m 2 h) for pristine ones. Salt rejection also measured 82% for virgin membrane and 63-90% for modified membranes. Moreover, FRR% were measured (~77% to ~93%), while the pristine membrane showed ~63% FRR%.

通过掺入亲水性CuO纳米颗粒来定制聚醚砜基NF膜的分离性能和防污性能

CuO/PES复合膜是通过转相法制备的，重点是减少污染和提高分离性能。氧化铜纳米颗粒用作膜结构中的填料添加剂。通过考虑 SEM、SOM 和 3D 表面图像研究嵌入的 CuO 纳米粒子对形态的影响。研究了通量回收率 (FRR%)、水接触角、水含量、机械拉伸强度、孔隙率和平均孔径、脱盐率和水通量，以评估制造的膜的性能。SOM 图像显示改性膜的表面均匀。SEM 图像显示出改性膜的指状结构。结果还表明在低浓度 CuO NPs 下膜的孔隙率和平均孔径增加，而在较高浓度的纳米粒子时发现相反的趋势。利用CuO NPs显着提高了膜的拉伸强度，通过在膜基质中应用CuO NPs显着提高了PWF。观察到 PES-0.05wt% CuO 混合膜的 PWF 最高 (42.63 L/m 2 h)，而原始膜的 PWF 为 10.41 (L/m 2 h)。原始膜的脱盐率也为 82%，改性膜的脱盐率为 63-90%。此外，测量了 FRR%（~77% 至~93%），而原始膜显示~63% FRR%。原始膜的脱盐率也为 82%，改性膜的脱盐率为 63-90%。此外，测量了 FRR%（~77% 至~93%），而原始膜显示~63% FRR%。原始膜的脱盐率也为 82%，改性膜的脱盐率为 63-90%。此外，测量了 FRR%（~77% 至~93%），而原始膜显示~63% FRR%。
