Abstract

original image

Ein supramolekularer Draht: Mit einem Polymergel umhüllte, meterlange, supramolekulare Drähte wurden in einem mikrofluidischen Kanal hergestellt (siehe Bild). Die selbstorganisierten Nanofasern in den Drähten richteten sich parallel zum laminaren Fluss aus. Die mechanische Stärke dieser Drähte war so groß, dass die Drähte auf einen Träger aufgebracht und als Templat zur Synthese unlöslicher, leitfähiger Polymere genutzt werden konnten.
