| Research Abstract |
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.
