The invention discloses a polyphenylene sulfide fiber composite NH2-UIO66 diaphragm and a preparation method thereof, and belongs to the technical field of water electrolysis hydrogen production. The preparation method of the polyphenylene sulfide fiber composite NH2-UIO66 diaphragm comprises the following steps: adding a composite solution for preparing NH2-UIO66 into a sulfonated polyphenylene sulfide fiber diaphragm, and carrying out hydrothermal reaction to obtain the polyphenylene sulfide fiber composite NH2-UIO66 diaphragm. The polyphenylene sulfide fiber composite NH2-UIO66 diaphragm disclosed by the invention has the advantages of low resistance (contributing to conduction of hydroxyl ions, improvement of conductivity and reduction of surface resistance), high hydrophilicity, high gas barrier property and the like. 本发明公开了一种聚苯硫醚纤维复合NH2-UIO66的隔膜及其制备方法，属于电解水制氢技术领域。聚苯硫醚纤维复合NH2-UIO66的隔膜的制备方法，包括以下步骤：在磺化处理后的聚苯硫醚纤维隔膜中加入制备NH2-UIO66的复合溶液，水热反应，得到所述聚苯硫醚纤维复合NH2-UIO6的隔膜。本发明的聚苯硫醚纤维复合NH2-UIO66的隔膜具有低电阻(有助于传导氢氧根离子，提高电导
