摘要

Fullerenes are promising candidates for intelligent, functional nanomaterials because of their unique mechanical, electronic and chemical properties. However, it is necessary to invent some efficient but relatively simple methods of producing structures composed of fullerenes for the development of nanomechatronic, nanoelectronic and biochemical devices and sensors. In this paper, we show that various structures such as straight fibres, networks formed by fibres, wide sheets and helical structures, which are composed of C_(60) molecules, are created by placing C_(60)-crystals in critical ethane, carbon dioxide and xenon even though C_(60) molecules do not dissolve or disperse in the above fluids. It is supposed, judging by the intermolecular potentials between C_(60) and C_(60), between C_(60) and ethane, and between ethane and ethane, that C_(60)-clusters grow with the assistance of solvent molecules, which are trapped between C_(60) molecules under critical conditions. This room-temperature self-assembly cluster growth process in critical fluids may open up a new methodology of forming structures built up with fullerenes without the need for any ultra-fine processing technologies.
