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** In the research and development of CNF, the use of electron microscopy for observation has become a necessary evaluation across almost all material fields and research phases. Particularly for observing CNF dispersed in polymers using TEM, it is essential to employ the technique of "electron staining," which has been crucial for preparing TEM samples of polymer materials. In this presentation, we will introduce examples of morphological observations of composite materials using CNF, as well as observation cases of the CNF itself, structural analysis examples such as crystallinity measured by 13C solid-state NMR, and examples of compositional sugar analysis using acid hydrolysis HPLC-fluorescence detection. **Table of Contents** 1. Introduction 2. Overview of Morphological Observation 3. Observation Cases of CNF and CNF/Polymer 4. Evaluation of CNF Crystallinity 5. Compositional Sugar Analysis of CNF (HPLC-Fluorescence Detection) 6. Conclusion

Technical Information Magazine The TRC News "Morphological Observation of Composite Materials Using Cellulose Nanofibers (CNF) and Structural Analysis of CNF" [Abstract] In research and development involving CNF, the use of electron microscopy for observation is a necessary evaluation across almost all material fields and research phases. Particularly, to observe CNF dispersed in polymers using TEM, it is essential to employ the technique of "electron staining," which has been indispensable for preparing TEM samples of polymer materials. This time, we will introduce examples of morphological observation of composite materials using CNF, as well as observation examples of CNF itself, and structural analysis examples such as crystallinity measured by 13C solid-state NMR and compositional sugar analysis using acid hydrolysis HPLC-fluorescence detection.
