摘　　要：聚苯硫醚(PPS)纤维具有良好的物理和化学性能,将成为最有前景的水电解制氢槽用隔膜替代原料之一。通过纺纱、织造工艺参数设计,制备出水电解制氢槽用PPS短纤维隔膜和长丝隔膜,随后进行热轧和磺化处理,并对两种隔膜的表面性能、强度、面电阻、电阻率、孔径、孔隙率、气密性、吸碱性能等主要指标进行测试。结果表明,PPS长丝隔膜的总体性能优于短纤维隔膜,具有更好的发展前景。Polyphenylene sulfide(PPS)fibers have good physical and chemical properties and will become one of the most promising raw material for water electrolyzer hydrogen production diaphragm replacement.Through the design of spinning and weaving process parameters,PPS staple fibers and filament diaphragm substrate cloth for water electrolysis hydrogen production tank are prepared,and then hot rolling and sulfonation are carried out,and the main performance indicators such as surface flatness,strength,surface resistance and resistivity,pore size and porosity,air tightness and alkali absorption performance of the two diaphragms are tested.The results show that the overall performance of PPS filament diaphragm is better than that of staple fibers diaphragm,which has better development prospects.
