| 摘 要： | 根据生物矿化原理,通过CO2的缓慢扩散,在硫酸软骨素(CSB)/L-谷氨酸二元体系中,与富集在有机/无机界面钙离子的结合,合成了不同形貌的碳酸钙.系统地研究了室温下各种因素对碳酸钙晶体形貌和晶型的影响.产物用XRD、SEM和FT-IR进行表征,FT-IR和XRD分析表明:所得的晶体为方解石的晶型,SEM表明体系中CSB的浓度,pH值,CSB/L-谷氨酸的浓度比对碳酸钙形貌起着重要作用.通过改变实验条件得到了椭球型,哑铃型等形貌碳酸钙晶体,并对其可能的形成机理进行了分析.

| Abstract: | Based on the basic principles of biomineralization,calicium carbonate crystallites with different morphologies were synthesized using enriched Ca2+ at organic-inorganic interfaces with slowly infused CO2 gas in a system of CSB(Chondroitin sulfate)/L-Glutamic acid(L-Glu).The effect of various experimental parameters on the morphology and polymorph of CaCO3 particles were systematically studied at room temperature.The products were characterized by XRD,SEM and FT-IR.The results of XRD and FT-IR showed that th... |
