| Calcite Crystals Growth Regulated by Polypeptide Langmuir Monolayer | |
| 摘要: 本文研究了聚β-苯甲基天门冬氨酸(PBA)Langmuir膜对碳酸钙成核和生长的诱导控制作用。在PBA Langmuir单分子膜作用下，我们得到形状规则、边缘清晰的花瓣状碳酸钙晶体。XRD分析表明所得碳酸钙晶体为沿(104)和(208)晶面取向生长的方解石晶型；AFM、TEM和SEM观察显示了方解石形貌的变化过程。结果表明多肽PBA Langmuir单分子膜对碳酸钙的结晶、生长取向和形貌具有良好的诱导和调控作用。 | |

| Abstract: In this paper, we studied the influence and control of the poly β-benzyl L-aspartate (PBA) Langmuir monolayer on the nucleation and growth of calcium carbonate. Calcium carbonate crystals with clear edge and petal-like crystal morphology were obtained under the PBA Langmuir monolayer. XRD results show that the crystal phase was calcite with orientated growth along (104) and (208) plane. AFM, TEM and SEM observations show the morphology change of calcite. Our results suggest that PBA Langmuir monolayer used as a template can induce and manipulate the nucleation and growth of calcium carbonate with various morphology and specific crystal orientation. | |
