Abstract

original image

Polyphenolverbindungen, die in Tee, Rotwein und Schokolade vorkommen, bilden auf Trägermaterialien dünne haftende Polyphenolfilme durch spontane Adsorption aus einer Lösung. Auf der Grundlage dieser Beobachtung wurde ein allgemein anwendbarer Prozess zur Oberflächenmodifizierung von festen, porösen und nanopartikulären Metall-, Keramik- und Polymermaterialien entwickelt (siehe Bild; ROS=reaktive Sauerstoffspezies).
