Biologisch inspirierte Superbenetzbarkeit – von der Grundlagenforschung zur praktischen Anwendung

Abstract

Das Maßschneidern von Benetzbarkeit ist in den Oberflächenwissenschaften zwar wohlbekannt, aber dennoch ein hochinteressantes Thema, das bei der Lösung von größeren praktischen Problemen von enormem Interesse ist. In letzter Zeit wurden sowohl in der Natur als auch in Experimenten verschiedene superbenetzbare Systeme entdeckt. In diesem Aufsatz stellen wir drei Arten von Superbenetzbarkeit vor: dreidimensionale, zweidimensionale und eindimensionale Materialoberflächen. Durch das Kombinieren verschiedener Superbenetzbarkeiten lassen sich neue funktionale Grenzflächensysteme generieren und in Bauteile integrieren, die anschließend zur Lösung von aktuellen und zukünftigen Problemen im Zusammenhang mit Ressourcen, Energie, Umwelt und Gesundheit verwendet werden können.

Nanostructured and oriented metal–organic framework films enabling extreme surface wetting properties

“…These intriguing superhydrophilic or superoleophobic surface characteristics are obtained by the combination of a precise chemical composition and hierarchical microstructuring of the surface [13–16]. Nowadays, modern surface technologies such as antifog or antifouling, oil-repellant coatings, self-cleaning surfaces and water-harvesting systems are inspired by nature’s designs [17–26]. The synthesis of artificial superhydrophilic surfaces can be achieved by a variety of routes, for example, sol–gel synthesis, electrochemical deposition, anodization, electrochemical polymerization, electrospinning, plasma treatment, chemical or hydrothermal methods, vapor deposition, layer-by-layer assembly or laser ablation [19,27–39].…”
