A method for making a graphene nanoribbon composite structure includes providing a substrate including a plurality of protrusions spaced apart from each other. A graphene film is grown on a growth substrate, an adhesive layer is on a surface of the graphene film away from the growth substrate. After removing the growth substrate, the graphene film and the adhesive layer are cleaned with water or an organic solvent. The graphene film, the adhesive layer, and the substrate are combined and then are dried, so that a plurality of wrinkles are formed near the plurality of protrusions. The adhesive layer is removed, and after etching a surface of the graphene film away from the substrate, the graphene films except for the plurality of wrinkles are removed, to form a plurality of graphene nanoribbons.
