Multidimensional Structural Analysis of Polymeric Materials by Scanning Transmission Electron Microscopy (STEM)

Abstract

Multidimensional structural analyses of polymer materials through scanning transmission electron microscopy (STEM) are utilized to investigate diverse structural factors, encompassing three-dimensional spatial structure, elemental composition, chemical structure, and even time-dependent structural changes. STEM-EDX-tomography facilitates 3D elemental mapping of silica-filled rubber blends. STEM-EELS/ELNES phase mapping enables chemical mapping of the phase separation in polymer alloys. In-situ STEM provides the capability for real-time observation of the failure process of the adhesive interface, employing a tensile strain specimen holder.
