Electrical Conductivity of Fullerene Derivatives

Abstract

In this paper electrical conductivity of fullerene derivatives was investigated. Compared with pure fullerene (molecule C60), which is an insulator (10-12 Sm-1), the measured C60(OH)24 shows several order of magnitude higher electrical conductivity. Both, endohedral Cu@C60 and CuO/C60 mixture exhibited good conductivity, which could be expected since they contain an excess of metal particles. Cyclic voltammograms of Cu@C60 were obtained. Carbon dust as a precursor for fullerenes extraction has electrical conductivity of the same order of magnitude as endohedral fullerenes.
