摘要:: 摘要：聚己二酸对苯二甲酸丁二酯（PBAT）因具有优良的生物降解性能和力学性能，具有广阔

的应用前景。但目前最主要的PBAT制备纯可降解塑料薄膜的生产成本高、综合性能不足，限

制了 PBAT的应用。为了 PBAT得到更好的应用，综述了 PBAT基材共混改性的研究进展，主

要从添加低成本材料和其它聚合物方面进行了归纳，旨在改进PBAT工艺技术提供研究依据。

Abstract: Polybutylene adipate terephthalate (PBAT) has a broad application prospect because of its excellent biodegradability and

mechanical properties. However, at present, the most important PBAT to prepare pure degradable plastic film had high production

cost and insufficient comprehensive performance, which limited the application of PBAT. In order to obtain better application of

PBAT, this paperreviewed the research progress of PBAT substrate blending modification, mainly summarized from the addition of

low-cost materials and other polymers, in order to provide research basis for improving PBAT process technology.
