Polysulfone (PSF) membranes containing TiO₂ were prepared by phase inversion. The membrane surfaces were modified by electron beam irradiation at energies of 3 and 10 MeV for irradiation doses of 10 and 50 kGy. Hydrophilic sulfonate groups were then introduced by single-step grafting using a binary monomer of acrylic acid (AAc) and sodium styrene-sulfonate (SSS). The surfaces of the modified membranes were characterized by analysis of water contact angles (WCA), surface energy (SE), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and scanning electron microscopy (SEM). Filtration performances were evaluated using bovine serum albumin (BSA) and NR serum. A membrane irradiated at 10 MeV and 50 kGy showed the highest hydrophilicity after AAc/SSS grafting, with a WCA of 35.2 degrees and SE of 60.1 mJ/m². After 2^nd cycle filtrations of BSA and NR serum, this membrane demonstrated flux recovery ratios of 97.8% and 95.9%, respectively. The rejection rates of total solid content (TSC) and total protein in NR serum were 72.1% and 91.5%, respectively.

通过相转化制备含有TiO ₂的聚砜(PSF)膜。 对于 10 和 50 kGy 的辐照剂量，膜表面通过 3 和 10 MeV 能量的电子束辐照进行改性。然后使用丙烯酸 (AAc) 和苯乙烯-磺酸钠 (SSS) 的二元单体通过单步接枝引入亲水磺酸盐基团。通过分析水接触角（WCA）、表面能（SE）、傅里叶变换红外光谱（FTIR）、X射线光电子能谱（XPS）、原子力显微镜（AFM）和扫描对改性膜的表面进行了表征电子显微镜（SEM）。使用牛血清白蛋白 (BSA) 和 NR 血清评估过滤性能。10 度辐照的膜 MeV和50 kGy在AAc/SSS接枝后亲水性最高，WCA为35.2度，SE为60.1 mJ/m ²。在 BSA 和 NR 血清的第 2 次^循环过滤后，该膜的通量回收率分别为 97.8% 和 95.9%。NR血清中总固体含量（TSC）和总蛋白的排斥率分别为72.1%和91.5%。
