A direct reaction with liquid bromine was used to prepare bromo fullerene C60 Br14-18. The brominated derivative reacted with previous lyprepared 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 bromo fullerene. FTIR analysis of all the obtained products was performed and also TG Aanalysis 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.
