摘　　要：通过功能化表面活性剂CDS胶束体系制备碳酸钙颗粒，有效的模拟生物矿化过程中的阳离子的摄取或富集问题。CDS和正戊醇之间的协同效应能够调控特定形貌碳酸钙的形成。同时，在室温、没有镁离子存在的情况下，观察到了一种新奇的相转变过程。The bound calcium ions on the surface of calcium dodecyl sulfate（CDS） self-assemblies simulate, more or less, the selective enrichment and / or extraction of mineral elements in biomineralization.. Though the fine turning of the ratio between water and alcohol can adjusted interaction between the polar groups and polar groups, polar groups and caldum ions. Simultaneously, the novel phase transformation of vaterite to aragonite was observed, implying the possible formation mechanism ofaragonite at room temperature and in the absence of magnesium ions.
