A novel polyethersulfone (PES) nanocomposite membrane incorporated with lanthanum vanadate (LaVO₃) nanosheets was fabricated based on phase inversion approach. The morphology and the performance of the fabricated nanocomposite membranes were systematically studied by ATR-FTIR, SEM, AFM, porosity, water contact angle, antifouling and rejection measurements. The resulting membranes showed an asymmetric structure with finger-like pores in which the surface roughness declined by adding different dosages of LaVO₃ nanosheets. Contact angle measurements proved that the hydrophilicity of the nanocomposite membranes significantly increased. Furthermore, the water flux of the resulting nanocomposite membranes markedly enhanced due to the nanosheets incorporation. Moreover, nanocomposite membranes showed remarkable antifouling properties (flux recovery ratio ~85%) in contrast with the bare PES (flux recovery ratio ~60%). The high retention of Solazol Red SP-3B (~99%) and Bovine serum albumin (BSA) (~99%) as well as the high permeation flux of the fabricated membrane unveiled the multifunctional character of the nanocomposite membrane for purification of dyes and proteins.

基于相转化的方法，制备了掺有钒酸镧（LaVO ₃）纳米片的新型聚醚砜（PES）纳米复合膜。通过ATR-FTIR，SEM，AFM，孔隙率，水接触角，防污和拒水率测量，系统地研究了制备的纳米复合膜的形貌和性能。所得的膜显示出具有手指状孔的不对称结构，其中通过添加不同剂量的LaVO ₃降低了表面粗糙度纳米片。接触角测量证明纳米复合膜的亲水性显着提高。此外，由于掺入了纳米片，所得纳米复合膜的水通量显着提高。此外，与裸露的PES（通量回收率〜60％）相比，纳米复合膜表现出显着的防污性能（通量回收率〜85％）。Solazol Red SP-3B（〜99％）和牛血清白蛋白（BSA）（〜99％）的高保留率以及制得的膜的高渗透通量揭示了纳米复合膜在染料和染料纯化方面的多功能性。蛋白质。
