PLA/PBAT (Poly (lactic acid)/Poly (butylene adipate-co-terephthalate)) blend is a biodegradable material commonly considered a potential alternative to polymeric products from petroleum sources. PLA is intrinsically brittle, endowed with a low elongation at break and poor impact strength that restricts its use for some applications while PBAT has high ductility, heat resistance, and impact resistance. However, PLA associated with PBAT results in an incompatible blend, due to poor interfacial adhesion. The compatibilization of PLA/PBAT can be improved through physical and chemical interaction between the components, and with exposure to ionizing radiation. Cellulose is the most abundant biodegradable polymer available and is considered the potential material to be used as reinforcement in sustainable composite materials, as well as nanocellulose while an alternative to synthetic nanoparticles. This review describes the state of the art of polymer blends of PBAT and PLA, in terms of manufacturability, compatibilization, biodegradation, radiation processing, and cellulose nanocrystal reinforcement.

PLA/PBAT（聚（乳酸）/聚（己二酸丁二醇酯-共-对苯二甲酸丁二醇酯））混合物是一种可生物降解的材料，通常被认为是石油来源聚合物产品的潜在替代品。PLA本质上很脆，断裂伸长率低，冲击强度差，限制了它在某些应用中的使用，而PBAT具有高延展性、耐热性和抗冲击性。然而，由于界面附着力差，PLA 与 PBAT 结合会导致不相容的混合物。PLA/PBAT 的相容性可以通过组分之间的物理和化学相互作用以及暴露于电离辐射来改善。纤维素是最丰富的可生物降解聚合物，被认为是可用作可持续复合材料增强材料的潜在材料，以及纳米纤维素，同时是合成纳米粒子的替代品。这篇综述从可制造性、相容性、生物降解、辐射加工和纤维素纳米晶体增强等方面描述了 PBAT 和 PLA 聚合物共混物的最新技术水平。
