| 摘 要： | 以模拟体液（SBF）为介质，采用仿生法制备了纳米羟基磷灰石（n-HA），通过原位聚合法制备了纳米羟基磷灰石／聚氨酯（n-HA／PU）复合材料。利用x射线衍射（XRD）、红外光谱（FT-IR）、热重分析（TGA）、扫描电镜（SEM）研究了n—HA和复合材料的结构和热稳定性、表面形貌特征。结果表明，在SBF中用浓度为0．200mol／L硝酸钙溶液制备出具有良好结晶度的n-HA，由此制备的n—HA／PU复合材料开孔率良好，有望成为一种性能良好的医用组织支架材料。

| Abstract: | Nano-hydroxyapatite （n-HA） powers were synthesized in the medium of simulated body fluid （SBF） by a biomimetic method. Nano-hydroxyapatite/polyurethane （n-HA/PU） composites were prepared by in-situ polymerization. The constitution, thermal stability of n-HA and n-HA/PU composites were analyzed by X-ray diffraction （XRD）,infrared spectroscopy（IR）, and thermo gravimetric analysis （TG）,, n-HA and n-HA/PU composites surface appearance were observed by scanning electron microscopy（SEM）. The results showed that n-HA had a good degree of crystallization in SBF with 0. 200 mol/L calcium nitrate solution, n-HA/PU composites had good porosity, and had a great potential use for medical tissue scaffold materials. |
