Summary: | The present invention relates to a method for preparing a hollow fiber membrane, the method comprising a step for spinning a spinning liquid into a wet type coagulation bath, the spinning liquid containing: a polymeric resin composition for substrate formation; a polymeric resin composition for surface coating, containing a vinylidene fluoride-based polymer resin, a good solvent, and graphene oxide; and a bore solution, to a hollow type polymeric substrate containing a vinylidene fluoride-based polymer resin, to a hollow fiber membrane formed on the hollow type polymeric substrate and comprising a porous surface coating layer.
La présente invention concerne un procédé pour préparer une membrane à fibres creuses, le procédé comprenant une étape pour filer un liquide de filage dans un bain de coagulation de type humide, le liquide de filage contenant : une composition de résine polymère pour la formation de substrat ; une composition de résine polymère pour le revêtement de surface, contenant une résine polymère à base de fluorure de vinylidène, un bon solvant et de l'oxyde de graphène ; et une solution d'alésage, dans un substrat polymère de type creux contenant une résine polymère à base de fluorure de vinylidène, dans une membrane à fibres creuses formée sur le substrat polymère de type creux et comprenant une couche de revêtement de surface poreuse.
