In this study, we prepared a PPS hollow fiber membrane using green porogenic agents, which did not involve any diluent. The trend of stress variation with stretching ratio was analyzed in detail, and the influence of the coupling of calcium chloride (CaCl2) and poly(ethylene oxide) (PEO) on the formation of the membrane was explained. The prepared PPS hollow fiber membrane exhibited good ethanolophilicity and a narrow pore size distribution. The PPS hollow fiber membrane had good liquid and gas permeability. The results showed that the prepared PPS membranes had good performance in protein separation applications (≥80%) and high breaking strength (24.7–34.2 MPa). The rejection rate of activated sludge, silicon dioxide (SiO2) and calcium carbonate (CaCO3) were 99%, and the rejection rate of Direct Black 19 (D19) dye was 93%. In addition, the prepared hollow fiber membrane has excellent resistance to acid, alkali, high temperature, and polar solvents. We found that the permeability and selectivity of the membranes treated at high-temperature, acid, alkali, and organic solvent, respectively, did not change much. Therefore, the prepared PPS hollow fiber membranes have the potential to be used for water treatment in an extreme environment.

熔融纺丝热拉伸法绿色制备聚苯硫醚中空纤维膜及多孔结构构建
在本研究中，我们使用绿色致孔剂制备了PPS中空纤维膜，该膜不涉及任何稀释剂。详细分析了应力随拉伸倍率的变化趋势，并解释了氯化钙（CaCl 2）与聚环氧乙烷（PEO）的偶联对成膜的影响。制备的PPS中空纤维膜具有良好的亲乙醇性和窄的孔径分布。 PPS中空纤维膜具有良好的液体和气体透过性。结果表明，所制备的PPS膜在蛋白质分离应用中具有良好的性能（≥80%）和较高的断裂强度（24.7-34.2 MPa）。活性污泥、二氧化硅(SiO 2 )和碳酸钙(CaCO 3 )的截留率为99%，直接黑19(D19)染料的截留率为93%。此外，所制备的中空纤维膜具有优异的耐酸、耐碱、耐高温、耐极性溶剂的性能。我们发现，分别经过高温、酸、碱和有机溶剂处理的膜的渗透性和选择性没有太大变化。因此，所制备的PPS中空纤维膜具有用于极端环境水处理的潜力。
