    摘要:

    采用逆向热致相分离(RTIPS)法制备亲水性聚醚砜(PES)/磺化聚砜(SPSF)平板膜。通过扫描电子显微镜、傅里叶变换红外光谱仪、纯水通量、牛血清蛋白(BSA)截留率、水接触角和长期运行测试研究了SPSF含量和不同凝胶浴温度对PES/SPSF平板膜性能和结构的影响。结果表明,SPSF和PES可以成功混合。非溶剂致相分离(NIPS)法制备的PES/SPSF平板膜呈致密皮层和指状截面结构,而RTIPS法制备的PES/SPSF膜具有均匀多孔表面和海绵状结构。RTIPS法PES/SPSF膜的纯水通量和BSA截留率均高于NIPS法。静态水接触角随SPSF的增加而减小。RTIPS法PES/SPSF膜在2%SPSF时获得最佳渗透性能,其纯水通量和BSA截留率分别为967 L/(m2·h)和79%。

    Abstract:

    Polyethersulfone (PES)/sulfonated polysulfone (SPSF) flat-sheet membranes were prepared by reverse thermally induced phase separation (RTIPS) method. Properties and structure of PES/SPSF flat-sheet membranes, which varied with SPSF content and coagulation water bath temperature, were investigated by SEM, ATR-FT-IR, pure water flux, BSA rejection rate, water contact angle and long-term test. The results show that SPSF and PES can be mixed successfully. The PES/SPSF flat-sheet membrane prepared by NIPS method has dense skin layer and finger-like cross-section structure, while the membrane by RTIPS has uniform porous surface and sponge-like structure. The pure water flux and BSA rejection rate of PES/SPSF membrane by RTIPS method are higher than those by NIPS method. The water contact angle decreases with the SPSF addition. The best permeation performance of PES/SPSF membrane by RTIPS is obtained at 2% SPSF, the pure water flux and BSA rejection are 967 L/(m2·h) and 79%, respectively. In summary, the addition of SPSF can improve the anti-fouling performance of PES/SPSF membrane, and the performance of PES/SPSF membrane prepared by RTIPS method is better than that by NIPS method.
