Abstract: Polymeric ionic liquids (PILs) are very promising materials to enable more environmentally stable high-density energy storage devices. Realization of PILs providing high environmental and mechanical stability while maximizing ion conductivity would be accelerated by an improved molecular level understanding of their structure and dynamics. Extensive evidence suggests that both mechanical properties and ion conductivity in anhydrous PILs are intimately related to the PILs’ glass formation behavior. This represents a major challenge to the rational design of these materials given that the basic nature of glass formation and its connection to molecular properties remains a substantial open question in materials science and condensed matter physics. Here I describe coarse-grained and atomistic molecular dynamics simulations probing the relationship between PIL architecture and interactions glass formation behavior and ion transport characteristics while establishing machine learning frameworks for rapid computationally-driven design of new materials.Bio: Tarak Patra is currently a post-doctoral appointee at the Center for Nanoscale Materials at Argonne National Laboratory. He received his PhD from IIT Kanpur in 2014. Patra worked in the Department of Polymer Engineering at the University of Akron as a post-doctoral fellow before moving to his current position. He employs theory molecular simulation machine learning optimization methods and high-throughput characterization to advance the understanding and design of polymers and other soft materials. He received 2012 CSIR senior research fellowship for his work on the phase behavior of polymer nanocomposites. He has co-authored a book chapter and over 15 journal articles in the broad area of polymer science and nanoscience. This seminar is compulsory for students registered for course CL 702 or CL 704.
