【摘要】：羥基磷灰石由于具有優(yōu)良的生物相容性和生物活性而被廣泛應用于骨組織修復和替代領(lǐng)域。而磷灰石的不同微觀結(jié)構(gòu)對其力學性能和生物學性能具有較大的影響,因此對其微結(jié)構(gòu)的控制顯得至關(guān)重要。水熱法是人為構(gòu)建高溫高壓的密閉環(huán)境,通過添加Ca源和P源,在較為極端的條件下合成具有較高的結(jié)晶性磷灰石晶粒。受仿生礦化的影響,高分子有機物由于具有磷灰石定向沉積的活性基團,因而被用于水熱法制備形貌新穎的磷灰石粒子。綜述了近年來不同種類有機物模板運用于水熱法的制備方法,探討了有機物調(diào)控磷灰石晶粒形貌和尺寸的規(guī)律以及展望了水熱法制備羥基磷灰石發(fā)展趨勢。
[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.
