摘要
该文以更加接近生物矿化的方法研究了蔗糖/精氨酸体系对碳酸钙晶体取向、形貌和晶型的控制作用。XRD分析表明,在蔗糖/L-精氨酸混合体系中合成的晶体主要为碳酸钙的球霰石晶型及少量的方解石型,在单独的蔗糖或L-精氨酸溶液中基本是球霰石晶型。SEM分析表明,蔗糖和L-精氨酸均可诱导形成特殊形貌的碳酸钙。实验结果表明,蔗糖/精氨酸体系对碳酸钙的生长取向、晶型和形貌有较好的控制作用,该研究为合成具有特殊形貌的仿生材料提供了参考。
A simple and green way was used to control the crystallization of calcium carbonate in the sucrose/L-arginine system. The growth orientation, morphology and polymorph of calcium carbonate crystal were studied. XRD analysis showed that the crystals were mainly vaterite and a small amount of calcite formed in the sucrose/L-arginine system. However, only the vaterite crystals were formed in the separate sucrose solution or L-arginine solution. SEM analysis showed that sucrose or L-argi- nine could induce the formation of calcium carbonate with a special morphology. The experimental resuits showed that sucrose/L-arginine had a better controll for the growth orientation of calcium carbon- ate as well as its morphology and polymorph. The method provided a positive guidance for the synthesis of biomimetic materials.
