摘　　要：在“双碳”战略目标下,可生物降解塑料已经被普遍应用于食品包装、医疗用品、农业薄膜等领域。但和传统塑料相比,可生物降解塑料高昂的成本和一些机械性能上的不足严重限制了其在生产生活中的广泛应用,共聚改性、共混改性作为提升可生物降解塑料性能的有效手段引起了人们的深入研究。本文选择三种典型的可生物降解塑料PBAT、PLA、PBS,对其共聚和共混改性方法进行了综述,并对发展趋势提出展望。With the"carbon peak and carbon neutrality"strategic goals being put forward,biodegradable plastics have been widely used in food packaging,medical supplies,agricultural films fields.However,compared with traditional plastics,the expensive cost of biodegradable plastics and the shortcomings of some mechanical properties have seriously limited their wide application in production and life.As effective methods to improve the performance of biodegradable plastics,copolymerization modification and blending modification have attracted in-depth research.This article selects PBAT,PLA,PBS,and the copolymerization and blend modification aspects of the three biodegradable plastics are reviewed to provide a theoretical basis for the development of biodegradable plastics.
