▎ 摘  要

The strong and tough nacre holds a fine "brick & motar" structure of an alternate arrangement of inorganic sheets and organic macromolecules. This structure has inspired the design and fabrication of inorganic-organic composite materials for decades. Graphene, with excellent mechanical, electrical, thermal and single atomic layer structure, is the ideal building block for nacre-mimetic materials. Recent progress of graphene-based nacre-mimetic layered materials was highlighted. The main assembling methods are layer by layer assembly, solution casting, filtration and liquid crystal wet-spinning. The main interlayer forces are van der Waals forces, hydrogen bonding, ionic coordination and covalent crosslinking. Graphene-based nacre-mimetic layered materials show much better mechanical properties than nacres. The strength and toughness can reach more than 5 times and 10 times those of nacres, respectively. The composite materials also shows multifunctions, such as electrical conductivity and chemical resistance.
