“…Gong et al [88] demonstrated a high-performance ternary bioinspired nanocomposite through a synergistic effect from 1D building blocks of double-walled carbon nanotubes (DWNTs) and covalent bonding of PCDO. The side view fracture morphology of the rGO-PCDO-DWNT nanocomposite film demonstrated the pull out of well-aligned DWNTs along the direction of tensile stress, as shown in Figure 7C 1 .…”

“…In addition, GO-based bioinspired nanocomposites after reduction always feature high electrical conductivity due to the repaired conjugated structures. For example, the rGO-PCDO-DWNT ternary bioinspired nanocomposite demonstrates an electrical conductivity of 394.0 S cm −1 , [88] and the rGO-PCDO-Ca 2+ nanocomposite fiber reaches an electrical conductivity of 292.4 S cm −1 . [15] Recently, Liu et al [19] reported a superb electrically conductive graphene fiber (GF) through introducing dopants such as ferric chloride (FeCl 3 ), bromine (Br 2 ), and potassium (K) into pure GF by a two-zone vapor transport method.…”

Over the eons of evolutionary time, natural materials, including nacre, bone, lobster cuticle, and many others, developed delicate multiscale structures demonstrating outstanding properties. These natural materials provide endless inspiration for the fabrication of novel bioinspired structural materials. Extensive research has revealed the mechanism responsible for natural materials' properties and shows that high-performance structural materials could be fabricated via bioinspired strategies. [1][2][3][4][5][6][7][8][9][10] With the quest to develop novel bioinspired materials, it is essential to refine some basic scientific principles that can guide bioinspired fabrication.Recent research has indicated that the amplification of natural materials' mechanical properties far beyond those of the components that comprise them originates mainly from: i) a hierarchical micro-/nanoscale architecture and ii) abundant effective interface interactions. Here, we follow the roadmap of "discovery, invention, and creation," as shown in Figure 1, to give insight into the development of bioinspired structural materials. In the "discovery" section, natural materials are described as a source of inspiration. Bioinspired nanocomposites can be invented to mimic or even to surpass natural materials' attributes, as described in the "invention" section. We illustrate how the basic principles could work for bioinspired nanocomposites with different building blocks and fabrication approaches. Finally, in the "creation" section, we review novel multifunctional nanocomposites with properties that natural materials rarely possess. To provide a vision and inspiration for future research, we conclude with our perspectives on new and promising directions in the field, along with problems remaining to be solved. Discovery: Natural Materials Orderly Hierarchical ArchitecturesNatural materials are made at ambient temperatures from a relatively small number of ingredients that exhibit rather meager properties. Almost all of them are composites with orderly hierarchical architectures that arrest crack propagation, thus preventing catastrophic failure. Insight into the architecture of a typical natural material is the key to understanding the superiority of the biomimetic strategy for making novel synthetic materials.Natural materials, including nacre, bone, and the lobster cuticle, exhibit excellent mechanical properties, combining high strength and toughness. Such materials have the added benefit of being light in weight. These advantageous features are due to such natural materials' orderly hierarchical architectures and abundant interface interactions. How to utilize these design principles created by nature to fabricate high-performance bioinspired nanocomposites remains a great research challenge. A logical roadmap for developing these nanocomposites can be described as "discovery, invention, and creation." Here, the discovery of the relationship between natural materials' design principles and such materials' extraordinary mechanical proper...

“…In addition, Isogai and coworkers modified nanofibrillar cellulose with 2,2,6,6-tetramethylpiperidinyl-1-oxyl and composited it with saponite platelets to form a ternary artificial nacre, which showed a tensile strength of 420 MPa and strain-to-failure of 10%. [32] Other 1D nanofibers such as carbon nanotubes, [33,34] vanadium pentoxide (V 2 O 5 ) nanofibers, [29] and zirconium diboride [35] were also used to enhance the mechanical properties. Specifically, the ternary artificial nacre reinforced by V 2 O 5 nanofibers showed good shapememory performance, as well as excellent strength and toughness, owing to novel synergistic fashion 1D and 2D blocks.…”

fabricated a montmorillonite clay (MTM)/poly(diallydimethylammonium) chloride polycation (PDDA) composite with nacre-like layer structure for the first time through sequential adsorption of organic and inorganic dispersions, [13] a typical layer-by-layer (LBL) method. The MTM/PDDA hybrid film with layer structure shows a fracture strength and strain of 105 MPa and 1%, respectively, approximately equal to that of nacre. Since then, more clay-based nacre-like films have been synthesized through the LBL method, and the mechanical properties are promoted by modifying the MTM [14] or crosslinking the polymer. [15] However, the thickness of the nacre-inspired films synthesized by the LBL method is limited to sub-10 µm as LBL is extremely time-consuming. [4] To increase the thickness of nacre-like films, efficient methods such as vacuum-assisted filtration, [16,17] electrophoretic-assisted deposition, [18] evaporation, [19,20] and dip-coating [21] have been developed in the following years. For example, the nacre-like MTM/poly(vinyl alcohol) (PVA) film with a thickness of over 200 µm, which is dozens of times thicker than films fabricated by LBL, can be synthesized through vacuum-assisted filtration, and its fracture strength and strain can be up to 160 MPa and 1%, respectively. [16] Recently, a much thicker clay-PVA composite (up to several millimeters) could be achieved by compressing and heating thin-layered films synthesized by evaporation. [22] Another typical method to produce bulk composites with layer structure is freeze-casting. [23][24][25][26] For instance, a lamellar Al 2 O 3 /poly(methyl methacrylate) (PMMA) composite with a size of dozens of centimeters showed a high combination of strength (flexural strength of 210 MPa) and toughness (32 MPa m 0.5 ), further surpassing the traditional structural materials. [23] In general, several methods have been developed since 2003 to synthesize nacre-inspired artificial composites with layer structures. However, the limitation of binary inorganic/organic hybrids still hinders further improvement of the mechanical properties of nacre-like artificial structural composites. [27] Recent progress in the synthesis of novel nacre-inspired structural materials, including ternary artificial nacre, artificial nacre reinforced by bridges, and those with a high content of hard phase, is discussed next, here, as a reference of the novel strategies for fabricating lighter, stronger, and tougher nacre-inspired structural materials. To give a comprehensive understanding, the perspective to develop next-generation lightweight and high-performance structural materials and their challenges is also included.For modern material engineering, one of the most ambitious goals is to develop lightweight structural materials with superior strength and toughness. Nacre, a typical biomaterial with high mechanical performance, has always inspired synthesis of high-performance structural composites. Here, the synthesis strategies for further enhancing the strength and toughness of novel nacre-insp...

“…In order to facilitate the corrosion protection of various metallic substrates, versatile alternative practical coatings are being continuously developed such as conducting/ electroactive polymers, [10,11] conventional polymers containing filler with large aspect ratio [12,13] and polymer coatings with superhydrophobic surface [14,15]. Recently, great attention is paid to the potential of applications on bio-mimetic materials with super-hydrophobic surfaces structure due to their diverse potential and unprecedented hierarchical surfaces [16][17][18][19][20][21][22][23][24][25][26]. Moreover, the studies of anticorrosive polymer coatings with roughly superhydrophobic or biomimetic surface attracted intensive research interests [27][28][29][30][31][32][33][34].…”
