PAN超滤膜的常压介质阻挡放电等离子体亲水改性

摘要利用常压介质阻挡放电（DBD）等离子体技术，在非对称聚丙烯腈（PAN）超滤膜的表面接枝含有亲水基团的丙烯酸（AA）和聚乙二醇甲基丙烯酸酯（PEG360OHMA），采用衰减全反射傅立叶变换红外光谱仪（ATR-FTIR）、水接触角测定仪和扫描电镜（SEM）表征膜的表面性质，牛血清蛋白（BSA）溶液过滤实验考察膜的抗生物污染性能。结果表明，常压DBD等离子体亲水改性的超滤膜具有良好的抗生物污染性能。

Abstract： To improve the antifooling performance of polyacrylonitrile (PAN) ultrafiltration membrane, acrylic acid (AA) and poly(ethylene glycol) methacrylate (PEG360OHMA) was grafted onto the surface of the membrane by atmospheric dielectric barrier discharge (DBD) plasma induced grafting. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), water contact angle measurements (WCA) and scanning electron microscopy (SEM) were used to characterize the chemical structure of the membranes. The anti-fouling performance of the membranes was evaluated by the bovine serum albumin (BSA) filtration protocol. The results showed that the modified membranes with excellent anti-fouling performance could be fabricated by the atmospheric DBD plasma technique.
