When designing polymers to achieve desired characteristics, such as toughness, elasticity, and resilience, you must not only consider the type of polymer, but also the mechanics of its macromolecular architecture.
Sergei Sheiko of North Carolina at Chapel Hill will first delve into the nuanced properties of polymer networks, including their modulus, strain-stiffening behavior, and swelling tendencies, all of which are intricately linked to the network's architectural configuration. Then, Adrianne Rosales of the University of Texas at Austin, will underscore the significance of viscoelasticity – a phenomenon embodying both solid and liquid properties. She will also elucidate the mechanical characterization of viscoelastic materials, employing shear oscillatory rheology techniques in both the linear and nonlinear regions.
Register now to gain a deeper understanding of the intricate world of polymer mechanics and its impact on material behavior.
This ACS Webinar is moderated by Dominik Konkolewicz of Miami University and Rachel Letteri of the University of Virginia and is co-produced with the ACS Division of Polymeric Materials: Science & Engineering (PMSE).
