    • An inorganic phase separation membrane and an application thereof in an oil-water separation relate to a field of a functional material technology, and more particularly to a super-hydrophilic and underwater super-oleophobic inorganic phase separation membrane with a micro-nano scale, a surface recombination, and mesh structure, wherein, a molecular sieve coating is formed on a porous substrate. The inorganic phase separation membrane can separate a variety of oils in several harsh water environments with a high efficiency, a low power loss, and a quick speed. The inorganic phase separation membrane can be used for a long time, and is easy to be reformed. The inorganic phase separation membrane of the present invention is formed by the porous substrate and the molecular sieve coating that forms on the porous substrate, wherein, an aperture size of the porous substrate is 20 μm-200 μm; a thickness range of the molecular sieve coating is 3 μm-50 μm; a mass ratio of the porous substrate to the molecular sieve coating is 100:1-5:1; the porous substrate is a stainless steel mesh, a copper mesh, an aluminum mesh, or a porous ceramic; and a framework type of the molecular sieve is LTA, SOD, FAU, MEL, CHA, MFI, DDR, AFI, BEA, or PHI.
    • 无机相分离膜及其在油水分离中的应用涉及功能材料技术的领域,更具体地涉及具有微纳米尺度的超亲水和水下超疏油无机相分离膜, 表面复合和网状结构,其中在多孔基材上形成分子筛涂层。 无机相分离膜可以在多个恶劣的水环境中以高效率,低功率损耗和快速的速度分离各种油。 无机相分离膜可长时间使用,易于重整。 本发明的无机相分离膜由多孔质基材和在多孔质基材上形成的分子筛涂层形成,其中多孔基材的孔径为20μm〜200μm, 分子筛涂层的厚度范围为3μm〜50μm; 多孔基材与分子筛涂层的质量比为100:1-5:1; 多孔基材是不锈钢网,铜网,铝网或多孔陶瓷; 分子筛的骨架类型是LTA,SOD,FAU,MEL,CHA,MFI,DDR,AFI,BEA或PHI。
