Abstract

Nanostructures based on fullerene C70 are of great interest due to their wide application in modern branches of science and technology. In this work, a method for synthesizing nanostructures of various dimensions (nanoaggregates and nanowhiskers) of fullerene C70, based on the self-organization of C70 molecules during the evaporation of droplets of a solution of fullerene in ethylbenzene on the substrate surface, is proposed and implemented for the first time. It has been established that the onset of C70 nanowhisker synthesis during evaporation of C70 solution droplets on the substrate surface depends on the substrate temperature. Experimental evidence is presented that an increase in both the C70 concentration in the solution and the substrate temperature leads to an increase in the geometric dimensions of C70 nanowhiskers. The stability of the resulting nanostructures to high temperatures has been determined. The results obtained provide the necessary information on the role of solution concentration and substrate temperature in the synthesis of one-dimensional nanomaterials.
