As an electron microscopic method on polymer composites without staining, annular dark-field scanning transmission electron microscopy (ADF-STEM) was examined on its effectiveness for making contrast and established for a quantitative analysis of nanoscale structures. Relatively low-angle scattering electrons were found to be available for the formation of contrast owing to a density difference, which was confirmed by image simulation. Thus, the density of nanoscale phases was expected to be identified by ADF-STEM such as the case of identification of glass transition temperatures for micro-phases.

环形暗场扫描透射电子显微镜（ADF-STEM）作为一种不染色的聚合物复合材料的电子显微镜方法，被用来研究其对比度的有效性，并被建立用于纳米结构的定量分析。相对低角度的散射电子被发现是可用于形成对比度，由于密度差，这是由图像模拟证实。因此，预期纳米级相的密度通过ADF-STEM来识别，例如识别微相的玻璃化转变温度的情况。
