依据生物矿化的基本原理, 以明胶为基质, 在动态条件下, 仿生合成碳酸钙/明胶复合材料. 扫描电子显微镜和能量分散X射线(SEM-EDAX)分析表明, 明胶基质中形成的碳酸钙完全不同于纯水中形成的碳酸钙, 具有独特的微观结构形态和取向. 明胶浓度不同, 晶体的形态、取向以及主要元素Ca, O和N的含量相差较大.

关键词: 明胶基质, 仿生合成, 碳酸钙, SEM-EDAX, 微观结构形态

Based on the basic principles of biomineralization, the CaCO3/gelatin composite can be synthesized by the biomimetic synthesis under dynamic conditions, using gelatin as the matrix. The results of scanning electron microscopy with an energy dispersive X-ray analysis system (SEM-EDAX) showed that the synthesized composite, which has special microstructure and morphology and certain orientation, was different completely from the calcium carbonate that was formed in the water. The morphology , orientation and contents of the main elements (calcium, oxygen and nitrogen) of crystal are quite different for various content of the gelatin.

Key words: gelatin matrix, biomimetic synthesis, calcium carbonate, scanning electron microscopy with an energy dispersive X-ray analysis system (SEM-EDAX), microstructure and morphology
