| 摘 要： | 为深入对骨组织中羟基磷灰石有序排列形成的了解,本研究采用水热条件结合模板法实现了羟基磷灰石纳米棒按一定的规律连生在一起,出现了取向连生现象.通过对其连生方式的分析发现了羟基磷灰石晶体在水热条件下生长存在各向异性,羟基磷灰石纳米棒在模板作用沿着其c轴易连生在一起.通过建立晶体生长过程模型,从而合理地解释了取向连生存在的规律性,为骨组织的仿生合成提供了理论基础.

| Abstract: | For the understanding of the orientation of hydroxyapatite(HAP)in bone,epitaxial growth of nano HAP was found under hydrothermal condition with a template.Anisotropic growth of HAP mono-crystal results in the epitaxial arrangement of HAP rods along c axis.The phenomenon was formed on the basis of the incorporation of crystal growth units of anionic coordinated polyhedra model. |
