Recently, poly (d, l-lactide) -poly (ethylene glycol) (PLA-PEG) block copolymers have been widely applied owing to the favorable biodegradability and biocompatibility.

聚乳酸-聚乙二醇嵌段共聚物因具备良好的生物可降解性和相容性而得到广泛应用。

So here we will take the way of the Equal Channel Angular Extrusion (ECAE) to process poly (d, L-lactide) to improve its properties.

本研究采用等通道转角挤压技术对聚(d, L -)乳酸进行自增强研究，并测试其增强后的降解性能。
