仿生合成六方形碳酸钙薄片

Biomimetic Synthesis of Hexagonal CaCO_3 Thin Pieces

研究用仿生合成方法,加入聚合物PA合成六方形碳酸钙薄片,并对反应时间、聚合物浓度等反应条件对产物形貌的影响进行探讨。用红外光谱仪(IR),扫描电子显微镜(SEM),投射电子显微镜(TEM)对合成样品的形貌、结构进行了检测。显示得到的产物为亚稳态的六方形球霰石。

Hexagonal calcium carbonate thin pieces were synthesized in the presence of polymer PA, using biomimetic synthesis method. And the reaction system factors were changed, such as the reaction time and concentration of polymer PA, as to find out the influence of these factors on morphology of the products. The morphology and structure of the products were characterized by fourier transfor infrared spectrometer（IR）, scanning electron microscope （SEM） and transmission electron microscope （TEM）. It was found that the products were hexagonal vaterite mescocrytal.
