Abstract

L’invention concerne un voile non-tissé, poreux et chargé électrostatiquement, adapté pour la filtration d'aérosols nano et/ou sub-microniques, comprenant une multiplicité de fibres d’au moins une composition C1, la composition C1 comprenant au moins 50% en poids d’au moins un polymère P1 à base du motif de répétition issu du fluorure de vinylidène (VDF), lesdites fibres de composition C1 ayant un taux de cristallinité en phase(s) polaire(s), préférentiellement en phase uniquement beta, d’au moins 50% en poids, par rapport à leur poids total. L’invention concerne également un procédé de fabrication du voile, une membrane comportant le voile ainsi qu’un procédé de lavage/stérilisation du voile ou de la membrane.
