【摘要】：羟基磷灰石由于具有优良的生物相容性和生物活性而被广泛应用于骨组织修复和替代领域。而磷灰石的不同微观结构对其力学性能和生物学性能具有较大的影响,因此对其微结构的控制显得至关重要。水热法是人为构建高温高压的密闭环境,通过添加Ca源和P源,在较为极端的条件下合成具有较高的结晶性磷灰石晶粒。受仿生矿化的影响,高分子有机物由于具有磷灰石定向沉积的活性基团,因而被用于水热法制备形貌新颖的磷灰石粒子。综述了近年来不同种类有机物模板运用于水热法的制备方法,探讨了有机物调控磷灰石晶粒形貌和尺寸的规律以及展望了水热法制备羟基磷灰石发展趋势。
[Abstract]:Hydroxyapatite is widely used in the field of bone tissue repair and replacement because of its excellent biocompatibility and bioactivity, and the different microstructure of apatite has great influence on its mechanical and biological properties. Therefore, it is very important to control its microstructure. Hydrothermal method is to construct a sealed environment of high temperature and high pressure by adding Ca and P sources. High crystalline apatite grains were synthesized under more extreme conditions. Under the influence of biomimetic mineralization, macromolecular organics had active groups of apatite directional deposition. Therefore, it has been used to prepare apatite particles with novel morphology by hydrothermal method. The regularity of organics controlling the morphology and size of apatite grain was discussed and the developing trend of hydroxyapatite prepared by hydrothermal method was prospected.
