| 摘 要： | 利用鸡蛋壳膜控制反应物的扩散速度,制备了不同形貌的CaCO3材料,模拟再现了生物矿化过程中Ca2 离子在有机物调制下形成不同形貌CaCO3的过程.由于壳膜内外表面结构不同,沉积在外表面得到由片状粒子组成的CaCO3晶体,而沉积在壳膜内表面得到由小粒子组成的多面体CaCO3晶体.利用X-ray粉末衍射(XRD)和扫描电镜(SEM)等测试手段对样品的物相、结构、形貌和尺寸进行了表征,并初步探讨了CaCO3的形成机理.

| Abstract: | An eggshell membrane was used to control the growth rate of CaCO3 and different structured calcium carbonate crystals were obtained by biomimetic synthesis.When the outer surface of the membrane faced the calcium chloride solution,sheet-like CaCO3 particle agglomerates formed on the outer surface of the membrane.While CaCO3 crystals composed of particles were obtained when the inner surface was facing the calcium chloride solution.The products were characterized using X-ray powder diffraction(XRD),and scann... |
