Abstract: 以氯甲基化双酚A型聚砜（PSF-CH2Cl）为大分子引发剂，通过原子转移自由基聚合（A TRP）法合成了以聚砜（PSF）为疏水主链、聚（聚乙二醇单甲醚甲基丙烯酸酯）［P(PEGMA) ］为亲水侧链的梳状两亲性共聚物PSF-g-P(PEGMA).FT-IR和 1H-NMR的表征结 果证实了两亲性共聚物的生成.将PSF-g-P(PEGMA)与PSF进行共混，通过浸没沉淀法制 备了共混超滤膜.研究发现，引入5 wt%的PSF-g-P(PEGMA)，共混膜的孔隙率和平均孔 径分别从65.9%和0.08 μm提高到81.9%和0.18 μm；将共混膜于90℃热水中浸泡24 h后，膜表面O/S从14.63提高到17.16；共混膜的亲水性和抗牛血清蛋白(BSA)吸附性能显著提 升.
