MXene/ZnO导电分离膜的制备及性能
Preparation and Performance of MXene/ZnO Conductive Separation Membrane
摘要
Abstract
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.关键词
