Heal thyself! Exponentially grown layer‐by‐layer‐assembled polyelectrolyte multilayer coatings, which are mechanically robust under ambient conditions, can autonomically repair cuts several tens of micrometers deep and wide when they are simply immersed in water or when water is sprayed on the coatings. The self‐healing ability originates from the high flowability of these coatings in water.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
