界面聚合是目前世界上用以大规模工业化生产复合膜最常用最有效的方法，采用

Interfacial polymerization is currently the most commonly used and most effective method for large-scale industrial production of composite membranes in the world. The composite membranes prepared by this method have many varieties and large yields. This method is the principle of interfacial polymerization first discovered and proposed by PW Morganl, that is, the reaction monomers polymerize at the interface of the two-phase solution that is immiscible with each other to form a high molecular polymer film. The two-phase monomers commonly used in this method are polyamines, polyphenols and polyacid chlorides, and the two-phase solvents commonly used are water and n-hexane. The most commonly used method of film formation is to immerse a support base film with a microporous or mesoporous structure in an aqueous solution containing polyamines, polyphenols or prepolymers, and then immerse them in an insoluble solution. Water or slightly soluble polyacid chloride monomer or prepolymer organic solution for a set time. At this time, a polymerization reaction occurs at the interface between the two-phase monomer water and the organic solvent, forming an ultra-thin polymer film with a dense structure attached to the surface of the support, which is also the functional separation layer of the composite film.

Interface aggregation is currently the most common and effective method used in the world for large-scale industrial production of composite film, the use of this method to prepare a variety of composite film, large yield. This method is P.W Morganl's earliest discovery and proposed interface polymerization principle, that is, the reaction monomer at the interface of the insoluble two-phase solution polymer reaction to produce polymer film. The two-phase monomers commonly used in this method are polyamine, polyphenol and polyamide chlorine, and the commonly used two-phase solvents are water and positive hexane. The most commonly used method of filmmaking is to impregnate a support body substrate with a microporous or mesopolytic structure in a water phase solution soluble in polyamines, polyphenols or pre-polymers, and then immerse in another - an organic solution that is insoluble in water or slightly water-soluble in polyamide chlorpyrifos or pre-polymers. At this time, the two-phase monomer water and organic solvent interface polymerization reaction occurs, forming an ultra-thin polymer polymer membrane with dense structure attached to the support body surface, which is also the functional separation layer of the composite film.

Interfacial polymerization is the most commonly used and effective method for large-scale industrial production of composite membranes in the world. The composite membranes prepared by this method have many varieties and high yield. This method is the principle of interfacial polymerization first discovered and put forward by P. W. Morgan, that is, the reaction monomer polymerizes at the interface of two-phase solution which is not mutually soluble to form polymer membrane. The two-phase monomers commonly used in this method are polyamines, polyphenols and polyacyl chlorides, and the two-phase solvents commonly used are water and n-hexane. The most commonly used method of membrane preparation is to immerse the support base membrane with microporous or mesoporous structure in the aqueous solution with polyamine, polyphenol or prepolymer, and then immerse it in the organic solution with another kind of insoluble or slightly soluble acyl chloride monomer or prepolymer for a fixed time. At this time, the polymerization reaction takes place at the interface between the two-phase monomer water and organic solvent, forming an ultra-thin polymer membrane with dense structure attached to the support surface, which is also the functional separation layer of the composite membrane.<br>
