The strong and tough nacre holds a fine brick motarstructure 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.
