摘　　要：聚乳酸(PLA)作为一种新型的生物可降解材料,来源广泛、加工性能良好,但其硬而脆的属性限制了其在一些领域的应用。近年来,人们采用多种方法对PLA进行增强增韧改性以获得最优性能。文中针对PLA的特性、功能化和高性能化的发展趋势,并结合笔者课题组有关PLA的工作,首先揭示了PLA增强增韧的机理,然后从化学改性和物理改性两方面介绍了PLA的改性方法,随后讨论了聚乳酸与生物降解型和非生物降解型聚合物组成的复合材料,最后总结了聚乳酸在绿色电子器件、生物医用材料、形状记忆功能材料等领域中的应用,并对其未来的发展形势做出了展望,为开发新型聚乳酸增强增韧策略提供新的方法和思路。As a bio-based biodegradable polymer material,polylactic acid(PLA)has a wide range of sources and good processing property.However,its low strength and toughness limit its application in many fields.In recent years,people have developed a variety of methods to reinforce and toughen PLA to obtain better performance.Herein,combined with our work,this review focused on the research advances in the reinforcing and toughening of PLA in recent years.First,the reinforcing and toughening mechanisms of PLA were introduced.Based on these,the strengthening and toughening methods of PLA were introduced from chemical and physical modification methods.Then the composites composed of PLA with biodegradable and non-biodegradable polymers were discussed.Moreover,this work summarized the applications of PLA in green electronic devices,biomedicine,bio-based shape memory polymers and other fields.Finally,the future developments and challenges of PLA were also discussed.This review aimed to provide directions and ideas for the development of new reinforcement and toughening methods.
