摘要 在水溶性壳聚糖/鸡蛋清的调控下,采用气相扩散法仿生制备出多种形貌的碳酸钙晶体。研究了Ca2+起始浓度、m壳聚糖∶m鸡蛋清质量比对碳酸钙形貌和晶型的影响。采用扫描电子显微镜(SEM)、红外光谱(FT-IR)及X射线衍射(XRD)等测试技术对获得的碳酸钙样品进行表征。XRD及FT-IR结果表明所得碳酸钙包括方解石和球霰石两种晶型,SEM观察表明Ca2+浓度及m壳聚糖∶m鸡蛋清质量比对碳酸钙形貌有重要的调控作用。 Water-soluble chitosan and egg white are used as additives to control the morphology and ploymorph of CaCO3 by a gas diffusion method.The influence of the concentration of Ca2＋ and different ratios of mchitosan：megg white on the polymorph and morphology of CaCO3 crystal are investigated.The samples of the obtained CaCO3 particles were characterized by a sequence of methods including scanning electron microscopy（SEM）,Fourier transform infrared（FT-IR） spectroscopy and powder X-ray diffraction（XRD）.The results showed that the samples were consisted of calcite and vaterite polymorphs,and the concentrations of Ca2＋ and the ratios of mchitosan：megg white had co-effect on the morphology and polymorph of CaCO3 crystals.
