Exploring Polymer Aging: Microscopy and Thermal Analysis — •Judith Bünte, Laila Bondzio, Karsten Rott, and Andreas Hütten — Universität Bielefeld, Dünne Schichten und Physik der Nanostrukturen, Universitätsstr. 25, 33615 Bielefeld
The analysis of polymers and their additives is essential for understanding material performance and longevity, particularly in the context of aging processes. This work emphasizes the synergistic application of advanced microscopy and thermal analysis techniques to investigate polymer composition, structure, and degradation behavior.
Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) were utilized to visualize the microstructural features of polymer matrices, as well as the distribution of particles within the polymer. TEM offered high-resolution imaging to reveal morphological details, while SEM enabled surface characterization. These imaging techniques were further augmented by Differential Scanning Calorimetry to analyze thermal properties.
Polymer aging was studied under controlled conditions to evaluate structural and compositional degradation over time. Changes in microstructure and thermal properties were correlated with aging-related alterations.
The integration of these analytical techniques establishes a robust framework for characterizing polymers and their additives. This approach yields valuable insights into the stabilizing role of additives, such as TiO2, in protecting polymers against environmental and thermal stressors.
