Abstract

original image

Heilt euch selbst! Durch schichtweisen Aufbau erzeugte mehrschichtige Polyelektrolytüberzüge, die unter Umgebungsbedingungen mechanisch robust sind, können selbständig über zehn Mikrometer tiefe und breite Schnitte in ihrer Struktur reparieren, wenn sie in Wasser eingelegt oder mit Wasser besprüht werden. Diese Selbstheilungsfunktion erwächst aus der hohen Fließfähigkeit der Überzüge in Wasser.
