| 摘 要： | 采用液相吸附法制备了羟基磷灰石/聚乳酸复合材料.液相吸附法工艺简便,不引入有机杂质,尽可能的减少了聚乳酸在高温下的热处理,避免了分子量的明显下降,并适合工业化生产.羟基磷灰石在复合材料中的分散均匀,与基体的界面结合良好.制备的复合材料有着较高的力学性能和合适的降解性能.

| Abstract: | The hydroxyapatite/poly lactide composite biomaterials were prepared by solution-adsorption tech- nique.The method avoided many disadvantages such as:interfusion of poisonous substances,nonuniformity dispersal of HA in PLA,low molecular weight of PLA.HA particles were uniformly dispersed in the PLA matrix and showed well adhesion with PLA matrix.Composite biomaterials had better mechanical properties and suitable decomposable capability. |
