Research progress of physical modification for high-performance PGA
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.
