碳酸钙材料的仿生合成及形貌控制
发布时间：2021-04-01 15:32
由有机组织调制生成无机矿物这种方法为材料设计提供了一条独特的途径。这些生物材料具有以往材料所不具备的奇异、精美的形貌。从结构上分析，这些生物材料是与有机大分子紧密结合的复合材料，并具有从纳米至毫米尺寸分布的多级结构。通常这些材料在温和的自然环境下，通过特别设计的有机大分子调控材料的晶化过程形成的。由于这些特别设计的有机大分子调控这些无机材料的成核与生长，并决定材料的力学特性，所以这些有机大分子在生物材料形成过程中起着极其重要的作用。虽然这些生物材料是在温和的条件下生成的，但其具有许多优良的力学性能，特别是在骨骼生长过程中。自然界通过有机大分子与无机物离子在界面处的相互作用的矿化机理来控制材料的结构与形貌，从而使无机物与有机体形成具有择优生长取向的精美复合物。这种在自然条件下形成的复合物是在一般实验条件下所不能合成的。 碳酸钙作为一种非常重要的无机材料，在工程上具有广泛的应用。但碳酸钙作为生物材料，其各项性能尤其是力学性能直到最近才引起了各学科的广泛研究。碳酸钙作为生物材料，其复合特性及形貌决定着它各项性能。所以本文的重点是利用仿生合成技术，合成出具有多种奇异形貌的碳酸钙材料。我们...
