通过能量过滤透射电子显微镜 (EFTEM) 中的电子光谱成像 (ESI)，可以同时对半结晶聚乙烯的结晶和刚性非晶区域进行成像。传统的明场和暗场成像模式主要提供有关与四氧化钌等经典染色剂发生化学反应的非晶体区域的信息。 ESI 对染色剂无法到达的结构进行成像的能力在嵌入 Lowicryl HM20 基质中的新生聚乙烯“烤肉串”的 TEM 显微照片中显示。
The simultaneous imaging of the crystalline and rigid amorphous areas of semi‐crystalline polyethylene is made possible by electron spectroscopic imaging (ESI) in an energy‐filtering transmission electron microscope (EFTEM). Conventional bright‐and dark‐field imaging modes mainly provide information about the non‐crystalline areas which react chemically with classical staining agents such as ruthenium tetroxide. The ability of ESI to image structures which are inaccessible to the staining agent is shown in TEM micrographs of nascent polyethylene ‘shish kebabs’ embedded in a Lowicryl HM20 matrix.
