Abstract

La présente invention concerne un film en fibres creuses à base de polysulfone comportant 20 à 25 % en poids d'une résine de polysulfone (A), 45 à 55 % en poids d'un solvant organique (B) et 30 à 35 % en poids d'un additif hydrophile (C), ledit film en fibres creuses présentant une structure spongieuse asymétrique, dans laquelle la taille des pores augmente sans interruption en allant d'une couche superficielle extérieure vers une couche superficielle intérieure, le rapport entre la taille des pores de la couche superficielle extérieure et celle de la couche superficielle intérieure variant de 1/10 à 1/10 000. L'invention concerne également un procédé de fabrication dudit film en fibres creuses à base de polysulfone comprenant les étapes consistant à préparer une solution non diluée de filage contenant une résine à base de polysulfone (A), un solvant organique (B) et un additif hydrophile (C) ; à préparer un coagulant interne ; à filer la solution non diluée de filage et le coagulant interne ; à former des pores ; et à procéder à un bobinage, l'étape de formation des pores étant achevée lorsque le temps de séjour total dans le bain de coagulation et le bain de lavage dépasse 90 secondes.
