摘要: 依据生物矿化的基本原理,在动态条件下以葡聚糖为模板,采用仿生的方法控制合成了具有独特形貌并含有少量葡聚糖的碳酸钙复合材料.用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、傅里叶变换红外吸收光谱(FTIR)和电导率测定等手段对所得的复合碳酸钙进行了形貌与结构表征.结果表明,所得CaCO3为文石晶型,外貌类似菜叶.进一步的研究发现,在CaCO3结晶过程中葡聚糖与CaCO3之间存在超分子相互作用,并讨论了这种作用的可能机理.

Abstract: Based on the basic principles of biomineralization,a novel aragonite calcium carbonate( CaCO3 ) compound material with a specific morphology was synthesized by biomimetic method under dynamic conditions. In our experiments, the glucan was used as the template. The obtained composite CaCO3 were characterized by using X-ray powder diffraction(XRD) analysis and scanning electron microscopy(SEM). Furthermore,according to the results of Fourier transform infrared spectroscopy(FTIR) and measurement of conductivity,the possible mechanism of supermolecule interaction between glucan and CaCO3 during the CaCO3 formation process was discussed.
