Technical Information Magazine 201902-01 Polymers Using DPC-STEM
The technical information magazine The TRC News provides the latest information on analytical techniques that are useful for research and development, solving production troubles, and quality control.
**Abstract** Differential Phase Contrast (DPC) - Scanning Transmission Electron Microscopy (STEM), one of the measurement techniques of STEM, enables the measurement of electric fields at microscopic regions. By applying this method to polymer alloys, we discovered that contrast of phase separation structures, which are difficult to observe with conventional electron microscopy, emerges. **Table of Contents** 1.
