When polymer materials are stretched, they bend, deform, and ultimately break. How do we understand this process and control it to yield better materials? This project explores how glassy structure, crystallinity, and entanglements affect polymer mechanics. Employing computational, theoretical, and data-science-driven techniques, we develop next-generation plastics and compatibilizers. This work is in conjunction with the Polymer Analytics and Circular Economy projects at NIST.
While branched polymers have many technological applications, the structural characterization of these polymers poses experimental challenges. Using in silico methods can solve these issues by allowing precise structural control and rapid fabrication of new materials. We generate relationships between polymer architecture and dilute solution properties such as the intrinsic viscosity, radius of gyration, and hydrodynamic radius. Working closely with experiments, we hope to use these relationships to improve recycling techniques. This work is part of the Macromolecular Architectures and Circular Economy projects at NIST
