摘要: 在PC和Chol/PC有序体中进行CaCO3沉淀反应,用X射线衍射和扫描电镜方法表征了反应物结构,研究了作为有机模板剂的不同分子有序体对CaCO3的晶型和形态的指导作用.在反胶束合成中出纳米级CaCO3颗粒.胆固醇对有序体有显著影响,进而影响此体系中形成的CaCO3晶型,可诱导生成3种CaCO3异构体:胶体CaCO3、球霰石和方解石.方解石含量随胆固醇含量增加减少.

关键词: 胆固醇(Cholesterol), 卵磷脂(PC), 有序体, CaCO3, 球霰石

Abstract: The CaCO3 were obtained by chemical reaction in different molecular ordered assemble systems of PC/Cholesterol. X-ray diffraction analyses showed that there are three types of CaCO3 in these systems: colloid CaCO3, vaterite, calcite. The cholesterol not only influences the structure of ordered system, but also influences powerfully crystal type of reaction product in these systems.The calcite decreased with the increase of concentration of cholesterol. SEManalyses showed that CaCO3 nanoparticles can be synthesized in PC/ether reverse micell.

Key words: Cholesterol, PC, Ordered assemble systemes, CaCo3, Vaterite
