“…Recently, some high-performance GANs have been constructed through the synergistic toughening of 1D nanofibrils, including cellulose nanocrystal (CNC), [170,171] NFC, [140] and CNTs, [141] etc. For example, Wen et al [170] utilized CNC to induce synergistic toughening effect with GO nanosheets, resulting in ultrastrong and highly conductive GANs.…”

The hierarchical interfacial architecture of nacre inspires the fabrication of novel high performance graphene‐based nanocomposites. Graphene has great promise for applications in aerospace and especially for flexible electronic devices, etc., due to its remarkable mechanical and electrical properties. Thus, it is significant to summarize the role of interface interactions in the construction of nacre‐inspired graphene‐based nanocomposites, which is the distinctive characteristic and important scientific progress of the review. This review first makes a comparison for the interfacial architecture of above biological materials and finds inspiration from nacre to design the interface in graphene‐based nanocomposites, which contains single interface interaction, synergistic interface interactions, and synergistic building blocks. Then, the focus is attached to the effect of different interfacial design strategies on the mechanical and electrical properties of state‐of‐the‐art GO‐based artificial nacres (GANs), including 1D fibers, 2D films, and 3D bulk materials. Additionally, the multifunctional GANs with such functions as fatigue resistance, fire retardant property, and smart nanogating, etc. are also discussed. Moreover, some potential applications and corresponding challenges and solutions of GANs are detailedly summarized. Finally, from the views of theoretical simulation and experimental research, a perspective on the roadmap of GANs in the future is also proposed.

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...

To improve the surface compatibility between hydrophobic poly(lactic acid) (PLA) and hydrophilic bamboo cellulose nanowhiskers (BCNWs), four commercial available silane coupling agents were employed to modify their interfaces with different concentrations (0, 1, 8, and 16 wt%). PLA/BCNW biocomposite films were fabricated by solution casting. The effects of silylated BCNW on the thermal, mechanical, and morphological properties of PLA biocomposites were investigated. The coupled reaction between coupling agents and cellulose via Si‐O‐C bonding and hydrogen bonding was confirmed. Both, tensile strength and tensile modulus, decreased with the four silane treatments. The maximum elongation at break values increased to 213.8, 111.3, 255.3, and 209.8% after 16 wt% A‐151, 8 wt% A‐1100, 8 wt% A‐174, and 8 wt% A‐189 silane treatments, respectively, with respect to 12.4% of the untreated composite. A wire‐drawing phenomenon was observed on the tensile fractural surface. Glass transition temperature and crystallinity decreased after the surface modifications. POLYM.
