The invention provides a method for imparting antiviral properties to a hydrophilic polymeric material comprising preparing a hydrophilic polymeric slurry, dispersing an ionic copper powder mixture containing cuprous oxide and cupric oxide in said slurry and then extruding or molding said slurry to form a hydrophilic polymeric material, wherein water-insoluble particles that release both Cu++ and Cu+ are directly and completely encapsulated within said hydrophilic polymeric material.
L'invention concerne un procédé pour conférer des propriétés antivirales à une matière polymère hydrophile, ce procédé consistant à préparer une boue polymère hydrophile, à disperser dans la boue un mélange pulvérulent de cuivre ionique contenant de l'oxyde cuivreux et de l'oxyde cuivrique, à extruder et à mouler cette boue pour former une matière polymère hydrophile, laquelle sert à encapsuler directement et complètement des particules insolubles dans l'eau libérant à la fois Cu?++¿ et Cu?+¿.
