NOVELTY - Preparation of copper sulfide/graphene nanocomposite material comprises adding graphene oxide to dimethyl sulfoxide, ultrasonically mixing to obtain 0.22 g/l solution, adding copper acetate, stirring, dissolving in solvent, heating at 160-180 degrees C for 6-8 hours, centrifuging, washing, and vacuum drying. USE - Method for preparing copper sulfide/graphene nanocomposite material (claimed). ADVANTAGE - The method uses common, cheap and readily available chemicals as raw materials, has mild reaction, and is simple.
