碳酸钙是最丰富的生物矿物材料之一,不同形貌、不同晶型的碳酸钙可适用于印刷、陶瓷、涂料、医学等不同领域。模板法因其可以有效地控制合成碳酸钙的形貌、结构和尺寸,而成为目前制备碳酸钙的重要手段之一。本文结合近几年模板法控制合成碳酸钙的发展,综述了利用小分子、天然生物大分子、凝胶体、微乳液、聚合物等介质作为软模板合成碳酸钙的研究进展,同时简述了硬模板法合成碳酸钙的研究进展,分析比较了各种介质作为模板调控碳酸钙的优缺点,综述了模板法制备碳酸钙未来发展的主要方向及面临的问题。在此基础上,指出深入系统研究模板法调控合成碳酸钙的作用机理,结合电化学等现代技术手段,不断完善调控碳酸钙的晶型和形貌的技术,成为未来研究的重点。
Calcium carbonate is one of most abundant biological minerals. Calcium carbonate with multi-morphologies and different polymorphs can be used in different fields,including printing, ceramics,paints,and medicine. The template method is preferable to other approaches for synthesis of calcium carbonate,as its morphology and polymorph can be effectively controlled by simply altering the nature of template and preparation conditions. This paper reviews the development in preparation of calcium carbonate by using small molecule,natural macromolecule,gel,microemulsion and polymer as soft templates. The synthesis of calcium carbonate by using hard template is also described. The main development directions and problems in preparing calcium carbonate are analyzed by comparing the advantages and disadvantages of various matrixes. Finally,preparation of calcium carbonate and other biomaterials with the template method is prospected. The mechanism of synthesis of calcium carbonate with the template method,and using electrochemistry and other modern technology to improve the technology of controlling polymorphs and morphologies of calcium carbonate should be focused in the future.
