NOVELTY - Preparing aluminum-graphene composite material involves immersing aluminum sheet in aqueous solution of dopamine having pH of 8-8.5 for 20-80 minutes. Dopamine is dissolved in distilled water to obtain solution. Aluminum sheet is removed from dopamine solution and then immersed in aqueous solution of graphene oxide for 2-6 hours. Graphene oxide is dissolved in distilled water to obtain solution. Obtained aluminum sheet is cleaned with water, and annealed at 100-300 degrees C for 0.5-3 hours. USE - Method for preparing aluminum-graphene composite material (claimed). ADVANTAGE - The method is simple, and requires simple equipment, and enables to prepare aluminum-graphene composite material that has excellent heat performance.
