ecently, tailoring properties by architecture design that changes the spatial distribution of reinforcement in matrix at
micro/nano-scale without changing constituents has attracted intensive attention in the community of composite. Natural
biological materials are characterized by combining simple constituents into a wide variety of composites with a maximum
of control over architecture on many length scales, exhibiting a remarkable range of mechanical and functional properties.
Understanding the role that multilevel architectures play in controlling properties of natural materials may serve as inspirations
for architecture design in composites. Metals can be strengthened by adding hard reinforcements, but such strategy usually
compromises ductility and toughness as well as electrical/thermal conductivity. In past few years, a bioinspired strategy has
been applied to surmount the dilemma in our research. By assembling copper nanoflakes cladded with graphene, graphene/
copper matrix composites with a natural nacre inspired nanolaminated architecture have been prepared. Owing to a combined
effect from the bioinspired nanolaminated architecture and improved interface bonding, a tradeoff has been made between
mechanical strength and ductility as well as electrical/thermal conductivity in graphene/copper matrix composites. The
bioinspired nanolaminated architecture enhances the mechanical strengthening and electrical/thermal conducting efficiencies
of two-dimensional graphene by alignment of graphene that orient to maximize performance for required loading and carrier
transporting conditions, and toughening by crack deflection. The strategy sheds light on the development of structural-
multifunctional integrated composites.
