| 英文摘要 | Investigating the evolution of the hierarchical crystalline structure in the injection-molded polymer is instructive to better understand the process-structure relationship, which is critical for the design and manufacture of polymeric products with high performance. A nondestructive and quantitative method based on small-angle X-ray scattering microtomography (SAXS-CT) was developed to reveal the three-dimensional distribution and evolution of the hierarchical crystalline structure in injectionmolded polylactide (PLA). Spatial distributions of the oriented lamella and morphological parameters in the bulk PLA parts with different shear durations have been successfully mapped and quantitatively analyzed, which were further confirmed by scanning electronic microscopy. The effect of oscillation shear flow on the evolution of the hierarchical crystalline structure has been revealed successfully. The method based on SAXS-CT may provide a reliable tool for the establishment of the relationship between the process technology and the inner structure of the injection-molded polymer. |
