Title
(DE) Template-gestütztes Musterbildungsverfahren von Nanofasern im Electrospinn-Verfahren und deren Anwendungen
Abstract
(DE)

Die Erfindung betrifft ein Verfahren für die Herstellung von ein-, zwei- und dreidimensional strukturierten, aus Polymernanofasern bestehenden, mikro- und nanoporösen Vliesen in einer beliebigen Form mit einem sehr großem Orientierungsgrad der Fasern durch eine vordefinierte leitfähige Schablone (Template) als Kollektor sowie die Verwendung der erfindungsgemäßen Vliese. Durch die über die Akkumulationszeit der Fasern einstellbare Ablagerungsdichte der mittels eines Elektrospinnprozesses erzeugten Nanofasern kann die dreidimensionale Strukturbildung gezielt beeinflusst werden.
