NOVELTY - Preparing polyamide-amine dendritic macromolecules/nano-graphene composite material involves adding 0.42g carboxylated graphene to 40mL deionized water, and then stirring obtained mixture at 40 degrees C for 4 hours. The solution is filtered, centrifuged and washed with deionized water. Polyamide-amine dendritic macromolecules are added to washed material, and stirred at 35 degrees C to obtain a mixture. The mixture is washed with deionized water, and then dried to obtain a mixed product. Cobalt(II) chloride and sodium borohydride are added to mixed product, and then stirred at 50 degrees C for 4 hours. USE - Method for preparing polyamide-amine dendritic macromolecules/nano-graphene composite material (claimed). ADVANTAGE - The method enables to prepare polyamide-amine dendritic macromolecules/nano-graphene composite material in an eco-friendly manner.
