Title
(DE) Artikel mit Schadstoffbarrierefunktion, Laminat und dazugehöriges Herstellungsverfahren
(EN) Article acting as a barrier to noxious agents, laminate and associated production method
(FR) Article agissant comme barrière contre des agents nocifs, laminé et méthode de production associée
Abstract
(EN)
An article (10) includes a porous membrane (11), a first selectively permeable (12) coating supported by the membrane (11) and a component protective against delamination of the selectively permeable coating (12) from the porous membrane (11) and/or any other coatings applied thereto. The first selectively permeable coating (12) includes an antichemical, antibiological, antiradiological and/or antimicrobial agent. The protective component may be provided alone, or as an element of the first selectively permeable coating, or, a second selectively permeable coating. A laminate (40) and methods of providing these are also provided.
