高性能PPS网基PSF-ZrO_(2)复合隔膜的制备及其性能研究

Preparation of high-performance PPS mesh-based PSF-ZrO_(2)composite separator and its application study

聚苯硫醚(PPS)网基聚砜(PSF)-氧化锆(ZrO_(2))复合隔膜作为一种新型的高性能碱性水电解制氢隔膜,具有良好机械性能、低面电阻和高化学稳定性等优点。采用预热压成型和浸没沉淀相转换法制备出复合隔膜,研究了铸膜液中PSF、ZrO_(2)纳米颗粒、聚乙烯吡咯烷酮(PVP)含量对隔膜性能的影响。分析比较了复合隔膜(命名为PPZS)和商业化Zirfon UTP 500隔膜的性能。结果显示PPZS复合隔膜的抗拉强度达到36.36 MPa,面电阻达到0.21Ω·cm^(2),泡点压力达到0.268 MPa,表现出优异的碱性水电解制氢综合性能。

Polyphenylene sulfide(PPS)mesh-based polysulfone(PSF)-zirconia(ZrO_(2))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 prepared by preheating compression molding and phase inversion precipitation techniques.The effects of the content of PSF,ZrO_(2)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 tensile strength of 36.36 MPa,an area resistance of 0.21Ω·cm^(2),and a bubble point pressure of 0.268 MPa,which exhibit excellent comprehensive performance in alkaline water electrolysis for hydrogen production.
