摘　　要：高性能生物降解材料聚乙醇酸(PGA)存在柔韧性差、加工困难和降解速率快等问题,物理改性是一种能够有效提高其综合性能且显著降低成本的简单易行的方法。主要综述了近十几年来国内外针对PGA性能缺陷及加工问题开展的共混改性研究进展,以及满足不同加工和应用要求的高性能PGA的改性技术与方法。添加物主要包括功能性助剂、可降解高分子聚合物及不可降解高分子聚合物,共混改性有效地提升了PGA的热稳定性、力学特性和生物相容性,调控了PGA的降解速率,并提升了PGA共混体系的相容性。The performance bugs of high-performance biodegradable polyglycolic acid(PGA)include poor flexibility,processing difficulty and fast degradation rate.Physical modification for PGA is a simple method which can effectively improve its comprehensive performance and significantly reduce its costs.The research progress of blending modification for PGA to solve its performance bugs and processing problems at home and abroad in recent years as well as the modification technologies and methods for high-performance PGA that meet different processing and application requirements are reviewed.These blends include functional additives,inorganic fillers,degradable polymers and non-degradable polymers,which effectively increase the thermal stability,mechanical properties,bio-compatibility of PGA,adjust the degradation rate and improve the compatibility of PGA blending system.
