| 摘 要： | 采用仿生矿化法,以明胶为模板剂,矿化合成不同形貌碳酸钙。采用FESEM、XRD和FT-IR技术对产物的组成和结构进行了表征,并通过明胶浓度、钙离子浓度和晶化时间的变化考察了明胶在碳酸钙矿化过程中的作用机制。结果表明:明胶和钙离子的物质的量比对产物结构有较大影响,随着物质的量比的逐渐减小,产物由致密球体结构转变为双螺形、类球形以及疏松球体结构;另外,明胶分子还可稳定球霰石晶相的存在,但最终由于球霰石向方解石晶相的转化导致了凹孔结构碳酸钙的出现。

| Abstract: | Biomineralization of calcium carbonate,an important inorganic biomaterial,has been extensively studied. In this paper,calcium carbonate was synthesized by biomineralization using gelatin as the matrix. The structural and morphological properties of the resulting CaCO3 materials were characterized by field emission scanning electron microscopy (FESEM),X-ray diffraction (XRD),and Fourier-transform infrared (FT-IR) spectroscopy. The effects of varying the concentration of gelatin,the concentration of calcium i... |
