The combination of integrated focused ion beam-scanning electron microscope (FIB-SEM) serial sectioning and imaging techniques with image analysis provided quantitative characterization of three-dimensional (3D) pigment dispersion in dried paint films. The focused ion beam in a FIB-SEM dual beam system enables great control in slicing paints, and the sectioning process can be synchronized with SEM imaging providing high quality serial cross-section images for 3D reconstruction. Application of Euclidean distance map and ultimate eroded points image analysis methods can provide quantitative characterization of 3D particle distribution. It is concluded that 3D measurement of binder distribution in paints is effective to characterize the order of pigment dispersion in dried paint films.
集成聚焦离子束-扫描电子显微镜（FIB-SEM）连续切片和成像技术与图像分析相结合，可对干燥漆膜中三维（3D）颜料分散进行定量表征。FIB-SEM 双束系统中的聚焦离子束可实现对涂料切片的精确控制，且切片过程可与 SEM 成像同步进行，从而为 3D 重建提供高质量的连续横截面图像。应用欧几里得距离图和最终侵蚀点图像分析方法可对 3D 颗粒分布进行定量表征。结论认为，对涂料中粘结剂分布的 3D 测量可有效表征干燥漆膜中颜料分散的有序性。
