Abstract[English]
A polyamide composite film and a preparation method therefor. The preparation method comprises the following steps: preparing a base film with a porous structure; applying an aqueous phase solution and an oil phase solution on the base film, wherein the oil phase solution and at least part of the aqueous phase solution are applied on opposite sides of the base film; and forming a polymer layer on the base film by means of an interfacial polymerization reaction of the aqueous phase solution and the oil phase solution, so as to form the polyamide composite film.[French]
L'invention concerne un film composite de polyamide et son procédé de préparation. Le procédé de préparation comprend les étapes suivantes consistant à : préparer un film de base ayant une structure poreuse ; appliquer une solution de phase aqueuse et une solution de phase huileuse sur le film de base, la solution de phase huileuse et au moins une partie de la solution de phase aqueuse étant appliquées sur des côtés opposés du film de base ; et former une couche polymère sur le film de base au moyen d'une réaction de polymérisation interfaciale de la solution de phase aqueuse et de la solution de phase huileuse, de façon à former le film composite de polyamide.[Chinese]
一种聚酰胺复合膜及其制备方法，该制备方法包括以下步骤：制备具有多孔状结构的基膜；在所述基膜上涂布水相溶液和油相溶液，所述油相溶液和所述至少部分水相溶液涂布在所述基膜上相对的两侧；所述水相溶液和所述油相溶液经过界面聚合反应在所述基膜上形成聚合物层，以形成聚酰胺复合膜。
