以乙烯吡咯烷酮-丙烯酰胺杯芳烃聚合物共混膜(CA/PVP)与小分子修饰剂氨基酸构建双模板体系,成功制备了具有不同形貌与超级结构的碳酸钙晶体材料。共混膜的有序界面与氨基酸起到了协同调控作用,成功诱导扇贝状、竖笛状等多种形态与晶型的碳酸钙晶体的形成,并借助SEM、XRD、FT-IR等技术考察了CA/PVP共混膜的配比、氨基酸的浓度以及溶剂的种类对碳酸钙的晶型与形貌。该研究为双模板体系中仿生合成复杂结构的无机材料提供了一条新的途径。
A calcium carbonate crystal material with different morphologies and super structures was successfully prepared by constructing a dual-template system with vinylpyrrolidone-acrylamide calixarene polymer blend membrane (CA / PVP) and small molecule modifier amino acids. The orderly interface of the blend membrane and the amino acid play a synergistic role in controlling the formation of various forms and crystal forms of calcium carbonate such as scallop and clavulanate. The SEM, XRD and FT-IR techniques were used to investigate the formation of calcium carbonate crystals. The ratio of CA / PVP blend membrane, the concentration of amino acids and the type of solvent on the crystal form and morphology of calcium carbonate. This study provides a new way for biomimetic synthesis of inorganic materials with complex structure in bimodal system.
