羟基磷灰石陶瓷(HA)与人体具有良好的生物相容性,能够与骨结合,可用于骨代替材料,但其机械性能欠佳,还有待提高。聚乳酸(PLA)具有良好的生物相容性和降解性能。现将二者复合制备了HA/PLA复合物,采用超声分散法制备不同比例的HA/PLA多孔复合材料,并对该材料进行了相关的表征。结果表明HA/PLA比例在70:100时获得孔隙率及综合性能较好的多孔材料。
Hydroxyapatite ceramic (HA) and the human body has good biocompatibility, can be combined with bone, can be used as a bone substitute material, but its poor mechanical properties, but also to be improved. Polylactic acid (PLA) has good biocompatibility and degradability. HA / PLA composites were prepared by the combination of the two. HA / PLA porous composites with different proportions were prepared by ultrasonic dispersion method. The relevant properties of the composites were characterized. The results show that when the ratio of HA / PLA is 70: 100, the porous material with better porosity and overall properties is obtained.
