摘要：

以聚醚砜（PES）为膜材料，N,N-二甲基乙酰胺（DMAc）为溶剂，以聚甲基丙烯酸甲酯（PMMA）、聚乙烯吡咯烷酮（PVP-58000）、聚乙二醇-聚丙二醇-聚乙二醇三嵌段共聚物（Pluronic F127）和乙酸乙烯酯与N-乙烯基吡咯烷酮的共聚物（P(vp-co-va)-50000）为添加剂，采用浸没沉淀相转化法制备聚醚砜超滤膜。考察了添加剂的种类对膜性能的影响。结果表明，当Pluronic F127质量分数为2.0%时，添加Pluronic F127的聚醚砜超滤膜具有较好的综合性能：其纯水通量可达578.4L/(m2•h)，与未添加Pluronic F127的膜比较有大幅度提升，BSA截留率可达96.7%，亲水性得到改善，膜的抗污染性能得到明显增强。

Polyethersulphone (PES) ultrafiltration membrane was prepared through immerse precipitation phase inversion method by using PES as membrane material, N,N-Dimethylacetamide (DMAc) as solvent, polymethylmethacrylate (PMMA), polyvinylpyrrolidone (PVP-58000), triblock copolymer (Pluronic F127) and copolymer of vinyl acetate and N-vinyl pyrrolidone (P(vp-co-va)-50000) as polymer additives. The effects of the additive type on membrane performance were investigated. Results demonstrated that the modified PES ultrafiltration membrane containing 2% Pluronic F-127 showed the optimal separation performance. The pure water flux was over 578.4 L/(m2•h), which is greatly higher than that of the pristine membrane, and the BSA rejection was over 96.7%. What’s more, the hydrophilicity and antifouling of the modified membrane were improved significantly.
