Abstract

Carbon nanostructures (CNSs) of different types (carbon nanotubes, fullerenes, and fullerene-like structures) are obtained by the method of electric arc evaporation of SIGE and FGDG-7 graphites in an inert gas (He). A comparative analysis of the characteristics of synthesized CNSs is performed. The optimal technological conditions for the synthesis of CNSs from graphite anode electrodes of comparable grades (SIGE and FGDG-7) are determined. Deposits of the plasma chemical synthesis have been studied. The structure of the synthesized carbon materials is studied by scanning and transmission electron microscopies, and it is shown that carbon nanotubes are formed during the evaporation of SIGE brand graphite even without the use of a catalyst. Differential-thermal, thermogravimetric and differential thermogravimetric analyzes are carried out, and the temperatures of the beginning of the interaction of the formed CNSs with oxygen in air are established. According to data of the photospectral analysis of the synthesis products, it is shown that the fullerene component obtained by the evaporation of SIGE brand graphite contains 10–12% of C60 and C70 fullerenes, which is not inferior to similar indicators of MPG-7 brand graphite. In view of the cheapness of SIGE brand graphite as compared to FGDG-7 graphite brand, it can be argued that carbon nanostructures synthesized from SIGE brand graphite have a lower cost. This fact is important for the synthesis of carbon nanostructures used as fillers in modern composites. In addition, the synthesis of low-cost fullerene and fullerene-like molecules is a great advantage for their study and use in modern materials, because new modern advanced nanotechnologies on the basis of fullerenes are beginning today to be created.
