Abstract

This investigation reflects the enhanced mechanical as well as degradation features of a blend (PLA/30PBAT) containing 70 wt% of polylactic acid (PLA) and 30 wt% of polybutylene adipate terephthalate (PBAT). The ZnO-modified composites of PLA/PBAT (PLA/30PBAT/2ZnO) were prepared by adding the 2 wt% of ZnO into PLA/30PBAT matrix. Adding ZnO into PLA/PBAT improved the tensile properties such as strength and elongation. The PLA/30PBAT/2ZnO composite shows a 26% increment in the tensile strength as compared to PLA/30PBAT and a 91% improvement in elongation at the break over PLA/30PBAT. Further, PLA/30PBAT/2ZnO composites exhibit 31.2% higher degradation than PLA/30PBAT. Overall, the PLA/30PBAT/2ZnO composite demonstrates a balanced combination of improved mechanical performance and moderate degradability.

zno改性PLA/PBAT复合材料:用于可持续包装的机械强度和生物降解性研究
这项研究反映了含有70 wt%聚乳酸(PLA)和30 wt%聚己二酸丁二酯(PBAT)的共混物(PLA/30PBAT)的增强机械和降解特性。在PLA/30PBAT基体中加入2 wt%的ZnO,制备了ZnO改性PLA/PBAT复合材料(PLA/30PBAT/2ZnO)。在PLA/PBAT中加入ZnO可以提高PLA/PBAT的强度和伸长率等拉伸性能。与PLA/30PBAT相比,PLA/30PBAT/2ZnO复合材料的拉伸强度提高了26%,断裂伸长率比PLA/30PBAT提高了91%。此外,PLA/30PBAT/2ZnO复合材料的降解率比PLA/30PBAT高31.2%。总体而言,PLA/30PBAT/2ZnO复合材料表现出提高机械性能和适度降解性的平衡组合。
