Abstract

Die Erfindung betrifft ein Verfahren zur Auftrennung von metallischen und halbleitenden einwandigen Kohlenstoff-Nanoröhren mit den Schritten: a) Suspendieren eines Materials, das sowohl metallische als auch halbleitende Nanoröhren umfasst, unter Beaufschlagung mit Ultraschall über einen Zeitraum von 1 Stunde bis 4 Stunden in einer Lösung aus Wasser und einem Salz von Dodecylsulfat, das sich hierbei bevorzugt an die metallischen Röhren anlagert, wodurch in der Suspension zwei Spezies von unterschiedlicher Größe vorliegen, und b) Trennen der beiden Spezies aufgrund ihrer unterschiedlichen Größen.
