以12-3-12/SDS混合系统为模板合成碳酸钙-环糊精复合材料

Preparation of calcium carbonate-cyclodextrin composite materials using 12-3-12/SDS mixed templates

双子型表面活性剂12-3-12与阴离子表面活性剂SDS混合系统在不同配比下生成不同的自组织体(包括胶束、囊泡、液晶)。分别以这些自组织体为模板,利用碳酸化法合成了具有贝壳珍珠层"砖-泥"结构的碳酸钙-环糊精仿生复合材料。以X射线衍射、红外光谱、扫描电子显微镜测试表征产品组成与形貌,通过不同类型的自组织体模板与碳酸钙-环糊精复合材料形貌的对比研究,探讨模板与材料形貌的关系,为新型材料的设计合成提供了新的思路。

Different self-assemblies in gemini surfactant 12-3-12/SDS mixed aqueous solution,including micelles,vesicles and liquid crystal,are used as templates to prepare calcium carbonate-cyclodextrin composite materials with brickand-mortar structures like nacre.Structure of materials was studied by XRD,IR and SEM experiments.Relation between materials' morphologies and templates was investigated,and some new ideas to design and prepare new materials are provided.
