Abstract

Feinstporieren von Kunststoffolien und anderen Materialien mittels Hochspannungsimpulsen findet ihre Grenze, wenn die materialspezifische Dielektrizitätskonstante oder die Dicke des Materials zu hoch ist.
Das erfindungsgemäße Verfahren sieht daher vor, die elektrisch nicht porierbaren Materialen (Kunststoffolie 2) in einem Nadelungsprozeß mit einer Vielzahl von Durchstichen (3) zu versehen, anschließend die Oberfläche der Folie (2) durch eine dünne, elektrisch porierbare Auflage oder Schicht (4) wieder zu verschließen, um dann diese Schicht (4) in einem Feintporierprozeß mittels Hochspannungsimpulsen im Bereich der Durchstiche (3) mit wasserdampfdurchlässigen, aber wasserdichten feinsten Poren (5) zu versehen.
