NOVELTY - Assembling an amine-functionalized graphene comprises preparing an electroless plating solution by sonicating 0.1-1 g graphene and 100 mL copper sulfate aqueous solution for 2 hours; pouring mixture in a copper three-necked flask, adding 100 mL sodium borohydride (NaBH4) solution, and reacting for 0.5-8 hours; washing the copper-modified graphene with distilled water and ethanol for 3 times, and oven-drying at 40 degrees C; and adding nano copper-modified graphene to diethylenetriamine, where the mass ratio of nano copper-modified graphene and diethylenetriamine is 0.005-0.012. USE - Method for assembling an amine-functionalized graphene (claimed). ADVANTAGE - The amine-functionalized graphene has improved high molecular material compatibility. The method is inexpensive, and has simple and stable operation.
