Beschreibung
Zusammenfassung:	According to the novel interfacial polymerization membrane forming method for accurately controlling the thickness of the membrane by adding the interlayer, the interlayer is added in a traditional interfacial polymerization method to serve as a reaction place of a monomer, the time of polycondensation reaction is replaced by controlling the thickness of the interlayer, and the controllability of the thickness of the membrane is achieved; the invention is characterized in that: (1) the oil phase, the water phase and the interlayer liquid are mutually insoluble, the oil phase monomer can only diffuse between the oil phase main body and the interlayer, and the water phase monomer can only diffuse between the water phase main body and the interlayer; (2) the thickness of the membrane is controlled by controlling the thickness of the interlayer, when the thickness of the membrane formed by condensation polymerization reaches the thickness of the interlayer and a compact separation layer is formed, diffusion conta
