摘　　要：依据生物矿化基本原理,以甲壳素为基质,仿生合成了一些有特定形貌的碳酸钙晶体。用扫描电子显微镜(SEM)、X射线粉末衍射仪(XRD)和红外吸收光谱分析(FTIR)等手段对所得产物进行了表征。结果表明,甲壳素基质中形成的碳酸钙晶体的微观形态结构不同于纯水中形成的晶体结构。随着甲壳素基质浓度的不同,所得CaCO3晶体的形貌发生了变化,表明甲壳素基质对碳酸钙晶体形成具有调控作用。这给我们合成不同特性CaCO3材料提供了研究和实践的空间。Based on the basic principles of biomineralization, the CaCO3 which has specific shapes can be synthesized by the biomimetic synthesis, using chitosan matrix as the matrix. The products are characterized by scanning electron microscopy（SEM） ,X-ray powder diffraction（XRD） analysis and FT-IR spectroscopy. The results show that the microstructure of the crystals produced in the chitosan solution is different from the microstructure of the products obtained in pure water. The morphology of CaCO3 crystals changes when the concentration of the chitosan is different. These show the chitosan matrix has effects on the CaCO3 crystals and they provide enough research space to synthesize CaCO3 materials with different properties.
