摘要

通过拉伸含有1-10%非晶化羟基磷灰石(HA)的聚乳酸(PLA)熔体，制备了热塑性聚合物复合材料。采用XRD、热分析和显微技术对复合材料的理化性质进行了研究。结果表明，PLA/HA复合材料通过直径为0.4 mm的喷嘴可以很好地挤压，在FDM方法的3D打印过程中保持其形状，可用于制造三维多孔生物材料。

Thermoplastic Composites Based on Polylactide and Calcium Phosphates

Thermoplastic polymer composites have been obtained by stretching a polylactide (PLA) melt containing 1–10% amorphized hydroxyapatite (HA). The physicochemical properties of the obtained composites have been studied by XRD, thermal analysis, and microscopy. It is shown that PLA/HA composites are well extruded through nozzles with a diameter of 0.4 mm, retain their shape during 3D printing by the FDM method, and can be used to create three-dimensional porous biomaterials.
