Block copolymers for nanomanufacturing, clean water, and renewable energy
Abstract – Block copolymers are synthesized by linking two (or more) chemically-distinct polymers with covalent bonds. The incompatibility between the different polymer “blocks” drives their self-assembly into nanoscale domains. Our group has studied this class of materials for applications in semiconductor lithography, membranes, and thin film electronics. I will present an example of our work for each of these three areas and show how a combination of real-space and reciprocal-space measurements can inform both materials design and process development.
Biography - Dr. Gila Stein received her BS in Chemical Engineering from Drexel University in 2002 and obtained a PhD in Chemical Engineering from the University of California, Santa Barbara, in 2006. She then joined the National Institute of Standards and Technology, where she was a National Research Council Postdoctoral Fellow in the Center for Nanoscale Science and Technology from 2007-2008. Dr. Stein moved to the University of Houston as an Assistant Professor of Chemical and Biomolecular Engineering in 2009, received the Henley Professorship in 2012, and was promoted to Associate Professor in 2015. She joined the University of Tennessee as the Prados Associate Professor of Chemical and Biomolecular Engineering in 2016.
Research projects in the Stein Group are largely focused on the design and characterization of functional polymer films. We use advanced spectroscopic techniques to study the relationships between processing, structure and performance in a variety of polymer systems. Current projects include: i) developing theoretically-informed models of reaction-diffusion processes in glassy polymer films, which is relevant to semiconductor lithography; ii) understanding thermodynamics of architecturally-complex polymer blends, which enables the design of new coatings and adhesives; and iii) controlling structure and function in ionic block copolymer membranes for water purification and gas separations.
