Fullerene C60, Graphene-Oxide and Graphene-Oxide Foil with Fullerene and their Bromination

Abstract

Abstract:A direct reaction with liquid bromine was used to prepare bromofullerene C 60 Br [14][15][16][17][18] . The brominated derivative reacted with previously prepared graphene-oxide (hereinafter GO), according to a method described by Hummer. The same method was used to oxidize graphite alone. The prepared graphite fullerene foil was brominated with liquid bromine and the graphene-oxide foil was reacted with bromofullerene. FT-IR analysis of all the obtained products was performed and also TGA analysis to investigate particularly their thermal stability. The brominated products demonstrate lower thermal effects when thermally decomposed which is caused by the retarding ability of bromine.
