Mineral-based bulk structural materials (MBSMs) are known for their long history and extensive range of usage. The inherent brittleness of minerals poses a major problem to the performance of MBSMs. To overcome this problem, design principles have been extracted from natural biominerals, in which the extraordinary mechanical performance is achieved via the hierarchical organization of minerals and organics. Nevertheless, precise and efficient fabrication of MBSMs with bioinspired hierarchical structures under mild conditions has long been a big challenge. This Perspective provides a panoramic view of an emerging fabrication strategy, matrix-directed mineralization, which imitates the in vivo growth of some biominerals. The advantages of the strategy are revealed by comparatively analyzing the conventional fabrication techniques of artificial hierarchically structured MBSMs and the biomineral growth processes. By introducing recent advances, we demonstrate that this strategy can be used to fabricate artificial MBSMs with hierarchical structures. Particular attention is paid to the mass transport and the precursors that are involved in the mineralization process. We hope this Perspective can provide some inspiring viewpoints on the importance of biomimetic mineralization in material fabrication and thereby spur the biomimetic fabrication of high-performance MBSMs.

块状结构材料的基质定向矿化

矿物基块状结构材料 (MBSM) 以其悠久的历史和广泛的用途而闻名。矿物固有的脆性是影响 MBSM 性能的主要问题。为了克服这个问题，从天然生物矿物中提取了设计原则，其中通过矿物和有机物的分层组织实现了非凡的机械性能。然而，在温和条件下精确有效地制造具有仿生分层结构的 MBSM 长期以来一直是一个巨大的挑战。该观点提供了一种新兴制造策略的全景图，即基质定向矿化，它模仿了一些生物矿物的体内生长。通过对人工分层结构MBSMs的常规制造技术和生物矿物生长过程的比较分析，揭示了该策略的优势。通过介绍最近的进展，我们证明了这种策略可用于制造具有层次结构的人工 MBSM。特别关注质量传递和矿化过程中涉及的前体。我们希望这个观点能够就仿生矿化在材料制造中的重要性提供一些启发性的观点，从而促进高性能 MBSM 的仿生制造。特别关注质量传递和矿化过程中涉及的前体。我们希望这个观点能够就仿生矿化在材料制造中的重要性提供一些启发性的观点，从而促进高性能 MBSM 的仿生制造。特别关注质量传递和矿化过程中涉及的前体。我们希望这个观点能够就仿生矿化在材料制造中的重要性提供一些启发性的观点，从而促进高性能 MBSM 的仿生制造。
