“…Recent studies have investigated the effects of pulp source (Tanaka et al 2016), fibril dimension and concentration (Agoda-Tandjawa et al 2010), mechanical treatments (Pääkkö et al 2007), ionic strength (Dong et al 2013), pH (Fall et al 2013), as well as addition of amphiphilic molecules (Quennouz et al 2016) on the rheology of CNF dispersions. Additionally, CNFs can also assist in preparation of homogeneous dispersions of a variety of fillers and pigments, such as carbon nanotubes (Hamedi et al 2014), reduced graphene oxide (Duan et al 2016), TiO 2 (Schütz et al 2012), and CaCO 3 (Lourenço et al 2016) nanoparticles.…”

We have investigated the steady-shear and viscoelastic properties of composite dispersions of cellulose nanofibrils (CNFs) with medium or high charge density and two different nanoclays, viz. rodlike sepiolite or plate-like bentonite. Aqueous dispersions of CNFs with medium charge density displayed significantly lower steady-state viscosity and storage modulus but higher gelation threshold compared with CNFs with high charge density. Dynamic light scattering (DLS) results showed that the apparent hydrodynamic radius of bentonite particles increased when CNFs were added, implying that CNFs adsorbed onto the amphoteric edges of the plate-like bentonite particles. The sepiolite network in CNF-sepiolite dispersions was relatively unaffected by addition of small amounts of CNFs, and DLS showed that the hydrodynamic radius of sepiolite did not change when CNFs were added. Addition of CNFs at concentrations above the gelation threshold resulted in drastic decrease of the steady-shear viscosity of the sepiolite dispersion, suggesting that the sepiolite network disintegrates and the rod-like clay particles are aligned also at low shear rate. The relative change in the rheological properties of the clay-based dispersions was always greater on addition of CNFs with high compared with medium charge density. This study provides insight into how the rheology of CNFnanoclay dispersions depends on both the nanoclay morphology and the interactions between the nanoclay and nanocellulose particles, being of relevance to processing of nanocellulose-clay composites.

Nature has evolved hierarchical structures of hybrid materials with excellent mechanical properties. Inspired by nacre’s architecture, a ternary nanostructured composite has been developed, wherein stacked lamellas of 1D vanadium pentoxide nanofibres, intercalated with water molecules, are complemented by 2D graphene oxide (GO) nanosheets. The components self-assemble at low temperature into hierarchically arranged, highly flexible ceramic-based papers. The papers’ mechanical properties are found to be strongly influenced by the amount of the integrated GO phase. Nanoindentation tests reveal an out-of-plane decrease in Young’s modulus with increasing GO content. Furthermore, nanotensile tests reveal that the ceramic-based papers with 0.5 wt% GO show superior in-plane mechanical performance, compared to papers with higher GO contents as well as to pristine V2O5 and GO papers. Remarkably, the performance is preserved even after stretching the composite material for 100 nanotensile test cycles. The good mechanical stability and unique combination of stiffness and flexibility enable this material to memorize its micro- and macroscopic shape after repeated mechanical deformations. These findings provide useful guidelines for the development of bioinspired, multifunctional systems whose hierarchical structure imparts tailored mechanical properties and cycling stability, which is essential for applications such as actuators or flexible electrodes for advanced energy storage.

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...
