Inspired by the nacreous layer of mollusk shells, the fracture behavior of multiscale composites that combine intrinsic toughness from a brick-and-mortar structure connected through nanoscale mineral bridges and extrinsic toughness arising from a brittle-ductile laminate architecture at the millimeter scale...
1(b). Thus, a reliable bending model of nacre-like composites should take the two effects into account. In this work, a general approach based on the DTS model under bending configuration was developed to describe the bending behaviors of nacre-like structure, i.e., bending deformable ...
In addition, compared to other bioinspired composites with nacre-like structures, our synthetic nacre-like glass samples fulfill the requirements for this work, including the precise control of internal size and architecture, the reproduction of large-scale tablet sliding and the mass production of ...
Bulk nacre-like composites with mineral nano-interconnectivity at the same length scale as in the biological material are produced using magnetic alignment... Madeleine,Grossman,Florian,... - 《Advanced Materials》 被引量: 7发表: 2017年 Mineral Nano‐Interconnectivity Stiffens and Toughens Nacre‐li...
The higher performance at higher impact velocities of the nacre-like composites is attributed to the hierarchical structure that enables both localized energy absorption by deformation of the metallic tablet and tablet interlocking due to the waviness and inter-layered delamination, which allows plastic ...
This method has the advantage of shorter processing time, as it requires only sintering once instead of twice as in the fabrication of conventional brick-and-mortar (BM) composites via freeze casting. By tuning the processing parameters, composites with different ceramic content and layer thickness ...

Nacre (seashells) and bone are frequently used as examples for how nature achieves this through biomineralized, hybrid organic-inorganic composites, highly optimized for specific functions. Unfortunately, it has proven extremely difficult to transcribe nacre-like clever designs into synthetic materials, in...
Inspired by nacre's sophisticated "brick-and-mortar" structure, multilayered polyether amine (PEA)/graphene oxide (GO) hybrid building blocks were incorporated onto the surface of carbon fiber via Layer-by-Layer (LbL) assembly to strengthen and toughen the interphase of composites. Impressive ...
Although recently reported 2D membranes have exhibited promising Li+ selectivity, as shown in Figure 5E, the selectivity of Li+/Na+ and Li+/K+ is still low (<2) for most porous materials including GO membranes and their functionalized composites, MXene membranes, zeolitic imidazolate frameworks ...
