Polyphenylene sulfide(PPS)mesh-based polysulfone(PSF)-zirconia(ZrO2)composite separator,as a new type of high-performance alkaline water electrolysis hydrogen production separator,has the advantages of good mechanical properties,low area resistance and high chemical stability.The composite separator was pre-pared by preheating compression molding and phase inversion precipitation techniques.The effects of the con-tent of PSF,ZrO2 nanoparticles and polyvinylpyrrolidone(PVP)in the casting solution on the performance of the separator were investigated.The performance of composite separator(Named PPZS)and commercial Zirfon UTP 500 separator were analyzed and compared.The results show that the PPZS composite separator has a ten-sile strength of 36.36 MPa,an area resistance of 0.21 Ω·cm2,and a bubble point pressure of 0.268 MPa,which exhibit excellent comprehensive performance in alkaline water electrolysis for hydrogen production.
