Title (EN) SURFACE MODIFIED POROUS MEMBRANE AND PROCESS
(FR) MEMBRANE POREUSE A SURFACE MODIFIEE ET PROCEDE
Abstract:
(EN) A porous membrane product is provided which is formed from a porous membrane substrate having its surface completely modified with a perfluorocarbon copolymer composition. The porous membrane product has substantially the same permeability as the porous membrane substrate.
(FR) L'invention concerne un produit à membrane poreuse, obtenu à partir d'un substrat de membrane poreuse dont la surface a été complètement modifiée au moyen d'une composition à base de copolymère de perfluocarbone. Le produit à membrane poreuse possède une perméabilité sensiblement égale à celle du substrat de membrane poreuse.
