摘　　要：聚乳酸(PLA)类高分子是一类重要的生物降解聚合物,羟基磷灰石(HA)是人体骨骼的基本成分,以PLA类高分子为基体、以HA为增强材料的HA/PLA复合材料是复合生物材料中无机/有机复合材料的典型代表,其具有良好的生物相容性,在骨修复领域有重要的应用。笔者在介绍HA/PLA类复合材料的制备、性能和应用等研究近况的基础上,指出使用新型的复合工艺、采用纳米级和改性的HA增强是其发展趋势。Polylactic acids (PLAs) are important biodegradable polymers, and hydroxylapatite (HA) is the basic component of human bones. PLAs as matrix and reinforced by HA, the HA/PLAs composites are typical representatives of inorganic/organic composite biomaterial. They have good biocompatibility and important applications in the field of bone repair. In this paper, the progress in recent years on their preparation, properties and applications are reviewed. It is pointed out that the researches on the using of novel preparation technology, nanometer or modified HA reinforcement, are development directions for HA/PLAs.
