为提高聚醚砜（PES）膜的亲水性能，以不同碱处理温度下的苯乙烯-马来酸酐共聚物（SMANa）作为添加剂，通过非溶剂诱导相分离法（NIPS）制备了SMANa/PES复合膜。在此基础上，利用真空抽滤的方法制备MXene/ZnO膜，对分离膜的结构、形貌和分离性能进行测试。结果表明：SMA转变为SMANa的同时，改善了与PES的相容性。当MXene的负载量为0.18 g/m²时，电导率高达0.73 S/cm。当ZnO的含量为15%时，水接触角由38.5°降低至22.4°。ZnO的加入不仅可以有效阻止MXene层与层之间的堆叠，而且还赋予导电分离膜优异的亲水性能。当ZnO含量为15%时，MXene/ZnO膜对刚果红染料的截留率由0 V的58.84%增加到1 V的77.07%，且渗透通量没有较大变化。

To improve the hydrophilicity of polyethersulfone (PES) membranes, SMANa/PES composite membranes were prepared by non solvent induced phase separation (NIPS) using styrene maleic anhydride copolymer (SMANa) at different alkali treatment temperatures as an additive. On this basis, the MXene/ZnO membrane was prepared using vacuum filtration method, and the structure, morphology, and separation performance of the separation membrane were tested. The results showed that the transformation of SMA to SMANa was accompanied by improved compatibility with PES. The electrical conductivity was as high as 0.73 S/cm when the loading of MXene was 0.18 g/m². When the content of ZnO further increased to 15%, the water contact angle decreased from 38.5° to 22.4°. The addition of ZnO not only effectively prevents the stacking between MXene layers, but also endows the conductive separation membrane with excellent hydrophilicity. When the ZnO content was 15%, the rejection rate of MXene/ZnO membrane for Congo red dye increased from 58.84% at 0 V to 77.07% at 1 V, and the permeate flux did not change greatly.
