The concern for the environment and sustainability has intensified the search for alternative materials to replace non-degradable plastics. Poly(butylene adipate-co-terephthalate) (PBAT) is a bioplastic that has been extensively studied due to its excellent mechanical properties, which are similar to those of low-density poly(ethylene) (LDPE). However, the high cost of this polymer still hinders its wider application. Among the different approaches that have been studied, blending PBAT with thermoplastic starch (TPS) could be an interesting solution to reduce the cost of the material and increase the degradability of the blends. This review covers most of the work reported in recent years on PBAT/TPS blends, including the effects of starch plasticizers, starch modifications, processing methods, use of chain extenders, various compatibilizers, and additives used for different applications.
对环境和可持续性的关注加剧了寻找替代材料以取代不可降解塑料的进程。聚（己二酸丁二醇酯-co-对苯二甲酸丁二醇酯）（PBAT）是一种生物塑料，因其优异的机械性能而受到广泛研究，这些性能与低密度聚乙烯（LDPE）相似。然而，这种聚合物的高成本仍然阻碍了其更广泛的应用。在已研究的不同方法中，将PBAT与热塑性淀粉（TPS）共混可能是一种有趣的解决方案，既能降低材料成本，又能提高共混物的可降解性。本综述涵盖了近年来报道的关于PBAT/TPS共混物的大部分工作，包括淀粉增塑剂的影响、淀粉改性、加工方法、扩链剂的使用、各种增容剂以及用于不同应用的添加剂。
