“…[86] In contrast, in the absence of polymer additives in solution, rhombohedral calcite crystals were obtained on the polysaccharides. [87,89] On glass substrates that are not coated with polysaccharides, no thin film formation was observed, even in the presence of acidic macromolecules. These results suggest that the cooperation of the polysaccharides and acidic macromolecules is essential for the thin film crystallization of CaCO 3 (Fig.…”

This article focuses on the synthetic approach to the preparation of calcium carbonate–organic hybrid materials, which are obtained by self‐organization processes under mild conditions. In these processes, organic molecules such as functionalized polymers and aligned amphiphilic molecules on the surface play key roles in the crystallization of calcium carbonate, which results in the formation of hybrid materials. As well as being environmentally benign, the hybrid materials have controlled morphology and unique properties. Materials scientists have obtained the ideas for the design of such hybrid materials from biominerals such as shells, teeth, and bones.

“…9 The cooperative involvement of insoluble and soluble macromolecules during crystallization of inorganic compounds seems to be a general strategy in biomineralization. 1 Nacre formation was mimicked by Kato et al [10][11][12][13][14] to synthesize polymer-CaCO 3 thin film composites. The combination of an insoluble solid matrix with soluble acidic macromolecules induces thin film crystallization of CaCO 3 on the matrix (Figures 1c and d).…”

It is increasingly important that we learn how to fabricate materials in environmentally friendly ways using common resources that are abundant in nature. Biomineralization, the process by which living organisms create a variety of sophisticated composites, such as bone and shell, is an ideal model for such fabrication. This article reviews recent progress toward the synthesis of polymer-inorganic composite materials inspired by biomineralization. In particular, three reaction systems are focused upon: (1) polymer-calcium carbonate thin film composites synthesized by interaction among insoluble polymer, soluble acidic polymer, and inorganic ions, (2) polymer nanogel-calcium phosphate composite nanoparticles synthesized on scaffolds of hydrogel nanoparticles and (3) colloidal silica nanoparticles made to self-assemble into anisotropic chain-like structures by interaction with block copolymers. All these reaction systems involve aqueous environments at ambient temperature and pressure.

“…For instance, template inhibition strategy can be applied in the production of thin films of CaCO 3 crystals, using soluble acidic polymers, such as poly(acrylic acid), as additives, which leads other polymers such as chitosan, chitin, and cellulose to act as a solid matrix in their presence. The obtained films thickness can reach values of ∼0.8 µm [82][83][84]. Combination with other techniques, such as the spin-coating, allows the production of layered polymer/calcium carbonate (CaCO 3 ) composite films [84].…”
