“…[1][2][3] In recent years, the advancement in aerospace, automotive, and shipbuilding industries has spurred the development of Al matrix composites with superior functional properties. [4][5][6] Graphene is a two-dimensional carbon material formed through sp 2 bonds. The intrinsic structural character of graphene endows it with many favorable properties, e.g., high interfacial affinity for metal based on its high specic surface area, excellent mechanical properties due to the sp 2 bonds, and attractive abilities in impeding atomic diffusion, which can be ascribed to its planar structure.…”
