Abstract

Ein beschichteter Nanopartikelverbund kann einfach hergestellt werden mittels einer kontinuierlichen Bildung von Wirtspartikeln und der Beschichtung einer dünnen Schicht auf der Oberfläche der Wirtspartikel unter Verwendung einer Vorrichtung, die umfaßt (a) einen zylindrischen Brenner, der einen konzentrischen Mitteldurchgang zum Einführen einer Wirtspartikelvorstufe und einen Flammen erzeugenden Kanal, der den Mitteldurchgang umgibt, umfaßt, der verwendet wird, um Wirtspartikel zu erzeugen; und (b) eine Beschichtungseinheit, die eine zentrale Öffnung zum Montieren des zylindrischen Brenners, einen ersten Einlaß zum Einführen einer Beschichtungsvorstufe, einen ersten Auslaß einer konzentrischen Röhrenform, der die zentrale Öffnung umgibt, der verwendet wird, um die Beschichtungsvorstufe in Kontakt mit Wirtspartikeln zu bringen, einen zweiten Einlaß zum Einführen eines Inertgases und einen zweiten, konzentrisch geformten Auslaß, der den ersten Auslaß umgibt, der verwendet wird, um die Beschichtungsvorstufe und Wirtspartikel mit dem Inertgas einzuhüllen, wobei der zylindrische Brenner am Boden der Beschichtungseinheit durch die zentrale Öffnung der Beschichtungseinheit montiert ist, so daß die Beschichtungseinheit nach oben und unten gleitet.
