Abstract

The application potential of fullerenes extends to the following areas: Owing to their similarity to active carbon the use of fullerenes as well as of the soot arising during their production in catalytic applications appears an interesting possibility. Structural modifications will permit influencing the catalytic properties of the employed substances. Addition of functional groups has led to a wide range of fullerne variants whose chemical properties and application potentials are still being studied. Polymers can be altered in their structure and properties by the integration of fullerenes. The possibility of increasing the photoconductivity of polymers in this way could be applied to photodetectors and solar cells, for example. Exposure to light causes fullerenes to polymerise and drastically reduces their solubility in commercial solvents. This may render them useful as a masking material in microstructuring. Diamond layers from fullerene vapour are very durable and can be manufactured in large sheets at comparatively low cost. In spite of their low density nanotubes are of incredible stiffness and as such an ideal component for composite materials. In monitors nanotubes can function as electron sources and replace the traditional cathode ray tube. A prerequisite for studying the properties of endohedral fullerenes is their availability  More>>

(orig./SR) [Deutsch] Folgende Anwendungspotentiale fuer Fullorene sind denkbar: - Die Verwandtschaft der Fullerene und des bei ihrer Erzeugung anfallenden Russes zur Aktivkohle sind fuer katalytische Anwendungen interessant, wobei die Katalyseeigenschaften durch Modifizierungen der Struktur veraendert werden koennen. - Mittlerweile stehen eine Vielzahl verschiedener Fulleren-Modifikationen durch Anbringen von funktionellen Gruppen zur Verfuegung, deren chemische Eigenschaften und Anwendungspotentiale weiter untersucht werden. - Durch den Einbau von Fullerenen in Polymere kann deren Struktur und Eigenschaften veraendert werden. Die Erhoehung der Photoleitfaehigkeit laesst sich z.B. bei Photodetektoren und Solarzellen einsetzen. Unter Belichtung polymerisieren Fullerene, wodurch sich ihre Loeslichkeit in den ueblichen Loesungsmitteln extrem reduziert. Anwendungen als Material fuer Masken bei der Mikrostrukturierung sind denkbar. - Diamantschichten aus Fulleren-Dampf sind sehr haltbar und koennen auch grossflaechig vergleichsweise guenstig hergestellt werden. - Fuer die Untersuchung der Eigenschaften endohedraler Fullerene ist das Vorliegen makroskopischer Mengen eine Voraussetzung. Vor einer Beurteilung des Potentials muessen zunaechst entsprechende Herstellungsverfahren entwickelt werden. - Nanoroehren weisen trotz ihrer geringen Dichte eine enorme Steifigkeit auf und sind daher ideal fuer den Einsatz in Verbundwerkstoffen. In Bildschirmen koennen Nanoroehren als Elektronenquellen fungieren und die bisher uebliche Kathodenstrahlroehre ersetzen. (orig./SR)}
