Title (EN) POROUS MEMBRANE AND METHOD FOR MANUFACTURING THE SAME
(FR) MEMBRANE POREUSE ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)Disclosed are a porous membrane having improved water permeability and elongation at break as well as high mechanical strength and impurity rejection rate and a method for manufacturing the same. The porous membrane of the present invention comprises a symmetric bead structure comprising a plurality of spherical crystallites. Each of the plurality of spherical crystallites comprises a plurality of sub-spherical crystallites.
(FR)L'invention concerne une membrane poreuse ayant une perméabilité à l'eau améliorée et un allongement à la rupture amélioré ainsi qu'une résistance mécanique élevée et un taux élevé de rejet d'impuretés, et un procédé de fabrication de cette membrane. La membrane poreuse de la présente invention comprend une structure à billes symétriques comprenant une pluralité de cristallites sphériques. Chacun des différents cristallites sphériques comprend une pluralité de cristallites sous-sphériques.
