Here, we employ molecular dynamics simulations to investigate the mechanical properties, deformation mechanisms, and failure behaviors of a representative Cu<sub>50</sub>Zr<sub>50</sub> NPGA under multiaxial loading. Our results reveal that the modulus of the NPGA increases markedly under multiaxial tension, while the ultimate tensile strength shows only a minor decline. Notably, the modulus strengthening effect in NPGAs is far more pronounced than that in traditional nanoporous gold (NPG), whereas the strength softening effect is considerably weaker. Both uniaxial and multiaxial tension deformations are governed by the combination of solid network bending and stretching, with the yield strength–solid fraction relationship conforming to the Gibson–Ashby model. Atomic-level analysis shows that the network skeleton undergoes elongation, yielding, necking, and rupture along the loading directions, with uniaxial tension generating a single fracture surface perpendicular to the loading direction and multiaxial tension inducing multiple fracture surfaces aligned with their respective loading axes. Quantitative analysis of atomic shear strain indicates that localized deformation and enhanced plastic strain lead to reduced yield strain and tensile strength under multiaxial loading.

In this study, bioplastic films were prepared from polybutylene adipate-<i>co</i>-terephthalate (PBAT), polylactic acid (PLA), and their blends using a blown film extrusion process. The effects on the samples were investigated for dosages of PLA and a compatibilizing agent (trade name: MBAX) on the melt flowability, surface morphology, mechanical properties, thermal behavior, chemical structure, and residue overall migration. Based on the results, the addition and the concentration of the compatibilizer effectively decreased the melt flowability of the PBAT/PLA compounds. In addition, the interfacial adhesion between the plasticized PBAT domain and the PLA matrix was enhanced by having a smooth surface. Based on the results of FTIR, there were no chemical reactions between the PBAT and PLA molecules, or with the compatibilizer within the blended films. The plasticized PLA/PBAT blown film prepared utilizing a blown film extrusion process had improved mechanical and thermal resistance. Furthermore, the addition of compatibilizer considerably increased the crystallinity of the PLA composites filaments up to approximately 160% compared with the neat PBAT film. The residue overall migration results for the neat PBAT and PLA films were within the regulated levels set by the European Food Safety Authority, suggesting that the developed products were appropriate for use in food packaging. On the other hand, the composite films at a ratio of PBAT-to-PLA-to-CaCO<sub>3</sub>-to-MBAX of 70:30:10:1 had residue overall migration greater than 10 mg dm<sup>−2</sup>, exceeding the regulations for food packing which was probably due to the CaCO<sub>3</sub>, with its hydrophilicity, dissolving within the blended films and reacting with the acetic acid in the food simulated solutions to produce calcium acetate, leading to migration into the food simulants. The main conclusion was that the PBAT/PLA blends, especially those containing 30%PLA, showed great potential to replace petroleum-based plastics and were suitable for film packaging applications.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 17","pages":"7410 - 7427"},"PeriodicalIF":3.5,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
