纳米羟基磷灰石及其复合材料的研究进展

Advances in nano-hydroxyapatite and its composite

纳米羟基磷灰石具有良好的生物相容性和生物活性,是较好的生物材料,被广泛应用于骨组织的修复与替代技术。但是,由于材料本身力学性能较差制约了羟基磷灰石的进一步应用,因此,提高及制备综合性能优越的纳米羟基磷灰石复合生物材料是当今研究的重心和热点。综述了纳米羟基磷灰石制备的主要方法及其复合生物材料的研究进展,并探讨了纳米羟基磷灰石骨修复材料的发展方向。

Nano-hydroxyapatite has been widely used as reconstructive and prosthetic material for osseous tissue, owing to its excellent biocompatibility and tissue bioactivity. But the poor mechanical property of hydroxyapatite restricts its further application. In order to enhance the comprehensive performance of the material, many researches have been dedicated to the synthesization of the composite materials. This article reviews the main preparation methods of nano-hydroxyapatite and the advancement in research of its composite. The directions in this research area are described as well.
