Jim Runt’s Expertise Summary (Nov '18): Although I retired from Penn State in July '18, I continue to be engaged in the scientific / technical side of polymer science and engineering. I am more actively seeking external consulting opportunities, including serving as an expert witness. I am also exploring Visiting Prof opportunities at universities in and outside of the U.S. The theme of my academic research was focused on polymer phase-separated morphology, and the relationship to polymer and ion dynamics. We frequently investigated the former using X-ray scattering. Dielectric spectroscopy has been used extensively in our investigations of dynamics, as it is a very sensitive probe of molecular motions over an ultrabroad frequency range and a wide temperature range. Publications related to the various research projects listed can be found at: https://scholar.google.com/citations?view_op=list_works&hl=en&user=MRN0IgkAAAAJ&gmla=AJsN-F5pgUFvcBX9wtepKp9rT-OfU7vY_ZKb7Cc6ZhLPbMoEx1Lcn5zXugYEzUDUYY44TKOq4hjTSzySS6BAGF4by7p2PpDFKLfOJKT2RDeVMZl9RIYVggE Some selected academic research topics included: 1. Polyurethane and polyurea segmented copolymers. Polyurethane chemistries have frequently been chosen to reflect those important in blood-contacting biomaterials applications. 2. Another effort involves my long-term interests in semi-crystalline polymers, particularly their crystalline microstructure, crystallinity and ultimate performance. Polymers investigated have run the gamut from polyolefins, PLA, aromatic polyesters (PBT, PET). One recent project focused on tailoring the dielectric properties of low dielectric loss polymers, for next generation polymer capacitor materials (e.g. ETFE, PFA, PEN). 3. For many years, we have been investigating ion and polymer dynamics of ionomers, some of which are relevant as solid-state electrolytes in power sources, actuators, and electrochemical devices.
