In this contribution, binary blends of thermoplastic starch (TPS) and poly(butylene trans-1,4-cyclohexanedicarboxylate) (PBCE) have been prepared by melt extrusion. The effect of different amounts of PBCE and the presence of citric acid as compatibilizer have been studied with respect to the blend behavior. In particular, morphological and thermal studies allowed for the determination of the compatibility between the blend components, and of their characteristic thermal transitions and thermal stability. Envisioning potential packaging applications, surface wettability, moisture absorption and migration of food simulant have been investigated. In addition, mechanical properties and gas permeability have been evaluated after conditioning the films in dry and humid environment.

为此，通过熔融挤出制备了热塑性淀粉（TPS）和聚（丁烯反式-1,4-环己烷二甲酸丁酯）（PBCE）的二元共混物。关于共混行为，已经研究了不同量的PBCE和柠檬酸作为增容剂的影响。特别地，形态学和热学研究允许确定共混物组分之间的相容性，其特征性的热转变和热稳定性。设想了潜在的包装应用，表面润湿性，水分吸收和食品模拟物的迁移。另外，在干燥和潮湿的环境中调节薄膜后，已经评估了机械性能和透气性。
