Abstract
Poly(lactic acid)(PLA)is considered one of the most promising sustainable bio-based polymers due to its renewability,biodegradability,excellent biocompatibility,high rigidity,high strength,and good processability.However,its inherent brittleness and poor ductility limit its widespread application.Researchers have focused on toughening PLA through various materials.Specifically,the research on toughening PLA using biodegradable materials has garnered significant attention and has achieved a series of important results.The article briefly introduces the synthesis and toughening mechanisms of PLA,and then reviews the latest research progress on the toughening of PLA using various biodegradable materials such as poly(butylene adipate-co-butylene terephthalate)(PBAT),poly(butylene succinate)(PBS),poly(butylene succinate-co-butylene adipate)(PBSA),poly(ε-caprolactone)(PCL),polyhydroxyalkanoates(PHA),poly(3-hydroxybutyrate)(PHB),starch and lignin,etc.,discusses the key factors and related toughening mechanisms,and finally points out the challenges and future development directions of toughening PLA with biodegradable materials.The review aims to provide some useful suggestions and guidance for subsequent sustainable research on toughening of PLA.关键词
