First, the polysulfone-sulfonated polysulfone blend material was synthesized by phase transfer emulsion polymerization. Then, the hollow fiber membrane was prepared by non-solvent induced phase separation followed by air drying. Finally, the microstructure of the membrane was controlled by changing the polymer concentration, coagulation bath concentration, and drying conditions, and its separation performance was tested. The expected result is a hollow fiber membrane with high separation efficiency and high flux, providing new materials and technical support for water treatment, gas separation, and biological separation applications.【Keywords】Seven-channel; Polysulfone-sulfonated polysulfone blend; Hollow fiber membrane; Microstructure control; Separation performance
