摘要

聚醚砜（PES）具有优良的化学稳定性，在许多领域得到了广泛的应用，但其较低的亲水性限制了其在水处理领域的应用。本研究以单宁酸（TA）为改性剂，采用浸渍法对PES中空纤维膜（PES-TA）进行亲水性改性。为解决TA易氧化为醌的问题，在TA溶液中加入羧甲基壳聚糖（CMCS）制备PES-TA-CMCS膜。随着CMCS用量的增加，膜的水接触角进一步减小，通量先增大后减小。当CMCS浓度为1.08 × 10−3mol/L时，PES-TA-CMCS的通量为105.72L/m2h，去除率为100.00%。一个月的氧化实验证明，PES-TA- cmcs的稳定性高于PES-TA。

Surface polymerization of tannins and carboxymethyl chitosan improves water purification of polyethersulfone hollow fiber membranes

Polyethersulfone (PES) has excellent chemical stability and has been widely used in many fields, but its low hydrophilicity limits its application in water treatment. In this study, hydrophilic modification of PES hollow fiber membranes （PES-TA) was studied by impregnation method with tannic acid （TA） as modifier. In order to solve the problem that TA is easy to oxidize into quinone, carboxymethylchitosan (CMCS) was added into the TA solution to prepare PES-TA-CMCS membrane. With the increase of CMCS amount, the water contact angle of the membrane further decreased, and the flux increased first and then decreased. The flux of PES-TA-CMCS was 105.72L/m²h and the rejection rate was 100.00 % when the CMCS concentration was 1.08 × 10⁻³mol/L. One-month oxidation experiments proved that the stability of PES-TA-CMCS was higher than that of PES-TA.
