Abstract:

The use of polymer materials has become increasingly popular in both academic and industrial fields, with applications ranging from common plastics to advanced biomaterials. With the advancement of computational science, simulations have become an essential tool for investigating the thermodynamics of molecular-level polymer systems. Along with great progress in properties prediction with improved accuracy, great challenges still exist in modeling processing of polymer systems, especially in accurate description of dynamic evolution incorporated with various processing conditions resulting macroscopic structural changes like carbon fiber processing from polyacrylonitrile (PAN) precursor in which crystalline regions represent more than 55% of the material by volume. 

During my talk, I will showcase how atomic-level simulations can lead to a more fundamental understanding of PAN crystal structures and guide you through an interactive Polymer Modeler powered by nanoHUB.
