“…7 LbL assembly is capable of fabricating polymer nanocomposites with exceptionally high contents of welldispersed nano-reinforcement (approximately 50-70 volume %), and with correspondingly high stiffness (tensile moduli as high as 15.7 to 125 GPa). [6][7][8][9][10] The total thickness of an LbL assembled film is determined by the number of times an alternating deposition cycle of anionic and cationic species is repeated, 11,12 but the nano-to microscale thickness per deposition cycle typical for LbL assembly is a major limitation of the technique and an impediment to utilizing the resulting materials for macroscale applications. 13 LbL assembly of conformal coatings onto three-dimensional porous templates, such as foams, colloidal crystals, and hollow tubes has been implemented for a variety of applications, [14][15][16][17][18][19] but these studies have largely focused on modifying the surfaces of these materials rather than altering the porous structure and bulk mechanical behavior.…”

The deposition of stiff and strong coatings onto porous templates offers a novel strategy for fabricating macroscale materials with controlled architectures at the micro-and nanoscale. Here, layer-by-layer assembly is utilized to fabricate nanocomposite-coated foams with highly customizable properties by depositing polymer−nanoclay coatings onto open-cell foam templates. The compressive mechanical behavior of these materials evolves in a predictable manner that is qualitatively captured by scaling laws for the mechanical properties of cellular materials. The observed and predicted properties span a remarkable range of density-stiffness space, extending from regions of very soft elastomer foams to very stiff, lightweight honeycomb and lattice materials.

Fusion of nacre, mussel, and lotus leaf: bio-inspired graphene composite paper with multifunctional integration

et al. 2013

Multifunctional integration is an inherent characteristic for biological materials with multiscale structures. Learning from nature is an effective approach for scientists and engineers to construct multifunctional materials. In nature, mollusks (abalone), mussels, and the lotus have evolved different and optimized solutions to survive. Here, bio-inspired multifunctional graphene composite paper was fabricated in situ through the fusion of the different biological solutions from nacre (brick-and-mortar structure), mussel adhesive protein (adhesive property and reducing character), and the lotus leaf (self-cleaning effect). Owing to the special properties (self-polymerization, reduction, and adhesion), dopamine could be simultaneously used as a reducing agent for graphene oxide and as an adhesive, similar to the mortar in nacre, to crosslink the adjacent graphene. The resultant nacre-like graphene paper exhibited stable superhydrophobicity, self-cleaning, anticorrosion, and remarkable mechanical properties underwater.

“…The adjacent MMT nanosheets could be bridged because of the electrostatic attraction for Ca 2+ and MMT nanosheets, leading to promotion of mechanical properties. [78] In addition, improved nacre-like films based on MMT could be obtained by introducing sodium carboxymethylcellulose and Cu 2+ via coordination bonding. [79] Yeh et al [80] discovered that GO paper prepared via an anodized aluminum oxide (AAO) filter disk reached a tensile strength of 100.5 MPa and a modulus of 26.2 GPa due to the crosslinking by Al 3+ generated from corrosion of AAO.…”

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...
