“…In other works, multilayers of TiO 2 and several kinds of polyelectrolytes (PEs) were fabricated by the combination of the LBL method and chemical bath deposition (CBD) [111,112]. CBD is a kind of self-mineralization process involving nanoparticle growth.…”

“…They also have the advantages of a mild processing route, using aqueous solution and popular molecules in ambient air at room temperature. Although the fabrication of bulk or film multilayer materials for use as structural components is quite difficult, some works combined self-organization and other coating techniques to obtain multilayers with submicrometer-thick layers in which a smaller nanoparticle structure is built, as introduced below [111][112][113]. The spontaneous formation of a hierarchical structure has a great advantage over any other method.…”

The structure and the toughening mechanism of nacre have been the subject of intensive research over the last 30 years. This interest originates from nacre's excellent combination of strength, stiffness and toughness, despite its high, for a biological material, volume fraction of inorganic phase, typically 95%. Owing to the improvement of nanoscale measurement and observation techniques, significant progress has been made during the last decade in understanding the mechanical properties of nacre. The structure, microscopic deformation behavior and toughening mechanism on the order of nanometers have been investigated, and the importance of hierarchical structure in nacre has been recognized. This research has led to the fabrication of multilayer composites and films inspired by nacre with a layer thickness below 1 µm. Some of these materials reproduce the inorganic/organic interaction and hierarchical structure beyond mere morphology mimicking. In the first part of this review, we focus on the hierarchical architecture, macroscopic and microscopic deformation and fracture behavior, as well as toughening mechanisms in nacre. Then we summarize recent progress in the fabrication of materials inspired by nacre taking into consideration its mechanical properties.

“…Setting the conditions such that these pathways can also be used in technical crystallization processes has lead to the generation of complex synthetic crystalline structures, which are indeed organic-inorganic hybrid materials, often exhibiting hierarchy. Mimicking nacre as a layered hybrid structure has been pursued within the Max Planck Society (MPS) [85][86][87][88][89], and elsewhere [90][91]. Indeed, nacre is a layered composite of calcium carbonate mineral and macromolecules with 3000-fold fracture resistance compared to the mineral itself.…”

“…Nacre has previously been retro-synthesized by recrystallizing the decalcified insoluble organic matrix of an abalone shell 13 . The organic-inorganic hybrid principle of nacre has been followed in the creation of several non-calcareous systems [14][15][16][17][18][19] .…”

Biomimetic layer-by-layer assembly of artificial nacre

et al. 2012

nacre is a technologically remarkable organic-inorganic composite biomaterial. It consists of an ordered multilayer structure of crystalline calcium carbonate platelets separated by porous organic layers. This microstructure exhibits both optical iridescence and mechanical toughness, which transcend those of its constituent components. Replication of nacre is essential for understanding this complex biomineral, and paves the way for tough coatings fabricated from cheap abundant materials. Fabricating a calcitic nacre imitation with biologically similar optical and mechanical properties will likely require following all steps taken in biogenic nacre synthesis. Here we present a route to artificial nacre that mimics the natural layer-bylayer approach to fabricate a hierarchical crystalline multilayer material. Its structure-function relationship was confirmed by nacre-like mechanical properties and striking optical iridescence. our biomimetic route uses the interplay of polymer-mediated mineral growth, combined with layer-by-layer deposition of porous organic films. This is the first successful attempt to replicate nacre, using CaCo 3 .
