Dr. Natalie Stingelin seminar
Dr. Natalie Stingelin, Chair of the School of Materials Science and Engineering and Director of the Center for Organic Photonics and Electronics at Georgia Institute of Technology, will deliver a department seminar, "Deciphering structure/property interrelations for functional polymer systems using thermal analysis" on Tuesday, December 12, 2023 at 1:25 p.m. in room B75 Amundson Hall.
In recent years, immense efforts in the functional polymer field have led to unprecedented progress and to numerous new opportunities for polymers in, e.g., electronics, energy storage, energy harvesting, health care, and beyond. Despite these advances, many challenges still exist: predicting properties, identifying reliable processing protocols and, more fundamentally, gaining a complete understanding of the way structural features over all length scales affect functions in macromolecular matter, including electron/ion transport, charge generation, ferroelectric characteristics, and/or photophysical processes. Here we demonstrate how classical polymer science tools can be used to elucidate the structure development of functional polymers from the liquid phase, how such knowledge can be exploited to manipulate their phase transformations and solid-state order and, in turn, their performance. We provide examples how side-chain softening can influence mechanical and optoelectronic properties, and how vitrification can dominate the structure formation of ferroelectric:semiconducting polymer blends. We moreover discuss how differential scanning calorimetry techniques, including fast calorimetry, can be used for the identification of thermodynamic transitions of “unusual” polymers, including hairy-rod polymers (used, e.g., in organic solar cells) or high-refractive index inorganic:organic hybrid materials. Generally, we will demonstrate how thermal analysis can be exploited to obtain important structural information of these new material classes and, in turn, how processing guidelines can be established towards materials of specific optical or electrical characteristics, towards improved materials design and new understanding of this next generation polymer systems.
Dr. Natalie Stingelin is a materials scientist and currently the Chair of the School of Materials Science and Engineering at the Georgia Institute of Technology (Professor since 2016; Chair since 2022). Prior to this, she hold positions at Imperial College London, Queen Mary University of London, the Philips Research Laboratories in Eindhoven, the Cavendish Laboratories, University of Cambridge, and the Swiss Federal Institute of Technology (ETH) Zürich.
