NOVELTY - A surface modified graphene flakes preparing method involves dispersing organic solvent with graphene oxide flakes, introducing an aluminum compound, stirring in the presence of dry or humid air, removing solvent and the residue, after drying, and decomposing the mixture thermally in the presence of air, at a temperature of 200-1200 degrees C, aliphatic hydrocarbons containing 3-9C or alkoxy in the case of the aluminum derivative and alcohols having 1-6C. USE - Method for preparing surface modified graphene flakes. DETAILED DESCRIPTION - A surface modified graphene flakes preparing method involves dispersing organic solvent with graphene oxide flakes, introducing an aluminum compound of formula (AlR3) or (Al (OR)3), stirring in the presence of dry or humid air, removing solvent and the residue, after drying, and decomposing the mixture thermally in the presence of air, at a temperature of 200-1200 degrees C, aliphatic hydrocarbons containing 3-9C or alkoxy in the case of the aluminum derivative and alcohols having 1-6C. R = 1-9C alkyl.
