The size, shape and distribution of different phases in thermoplastic polyolefin (TPO) blends and composites are critical to the properties of the materials, but can be difficult to characterise. Here we report the combination of heavy metal staining and focused ion beam - scanning electron microscopy (FIB-SEM) to reveal the three-dimensional (3D) structure of an elastomer-modified poly(propylene) and a talc filled elastomer-modified poly(propylene). High-quality, high-resolution serial images were collected and the 3D structures were characterised quantitatively.
热塑性聚烯烃（TPO）共混物和复合材料中不同相的尺寸、形状和分布对材料性能至关重要，但难以表征。在此，我们报道了重金属染色与聚焦离子束-扫描电子显微镜（FIB-SEM）相结合的方法，以揭示弹性体改性聚丙烯和滑石填充弹性体改性聚丙烯的三维（3D）结构。收集了高质量、高分辨率的系列图像，并对3D结构进行了定量表征。
