Abstract
(EN)
Provided are a supramolecular composite nano-filtration membrane and a preparation method therefor and the use thereof. The supramolecular composite nano-filtration membrane comprises: a base layer and a modification layer covering a surface thereof. The modification layer is a polymer layer with cucurbituril distributed therein; and the base layer is an organic membrane. The preparation method comprises the following steps: a first monomer and cucurbituril are dissolved into a first solution to obtain a first phase; a second monomer is dissolved into a second solution to obtain a second phase; the first phase is applied onto the base layer; the second phase is then applied onto the first phase; and an interface polymerization reaction is carried out, so as to obtain the composite nano-filtration membrane used for liquid filtration.

La présente invention concerne une membrane de nano-filtration composite supramoléculaire celet son procédé de préparation et son utilisation. La membrane de nano-filtration composite supramoléculaire comprend : une couche de base et une couche de modification recouvrant une surface de celle-ci. La couche de modification est une couche polymère avec du cucurbiturile distribuée à l'intérieur de celle-ci; et la couche de base est une membrane organique. Le procédé de préparation comprend les étapes suivantes : un premier monomère et du cucurbiturile sont dissous dans une première solution pour obtenir une première phase; un second monomère est dissous dans une seconde solution pour obtenir une seconde phase; la première phase est appliquée sur la couche de base; la seconde phase est ensuite appliquée sur la première phase; et une réaction de polymérisation d'interface est effectuée, de façon à obtenir la membrane de nanofiltration composite utilisée pour la filtration de liquide.
