Abstract

Procédé de fabrication d'un dispositif séparateur à fils creux poreux, convenant notamment pour une plasmaphérèse, dans lequel les pores dans les fils creux en un polymère avec une résistance chimique et thermique élevée sont créés par un bombardement des fils avec des particules chargées, en particulier des ions, suivi d'une attaque chimique qui transforme les sites bombardés en pores ouverts, dont le diamètre peut etre déterminé par la durée de l'attaque chimique.
