Simulation Study of the Effects of Polymer Network Dynamics and Mesh Confinement on the Diffusion and Structural Relaxation of Penetrants
Tsai-Wei Lin, Baicheng Mei, Kenneth S. Schweizer +1
The diffusion of small molecular penetrants through polymeric materials represents an important fundamental problem, relevant to the design of materials for applications such as co…
Self-Consistent Hopping Theory of Activated Relaxation and Diffusion of Dilute Penetrants in Dense Crosslinked Polymer Networks
Baicheng Mei, Tsai-Wei Lin, Charles E. Sing +1
We generalize and apply a microscopic force-level statistical mechanical theory of the activated dynamics of dilute spherical penetrants in glass-forming liquids to study the influ…
How Segmental Dynamics and Mesh Confinement Determine the Selective Diffusivity of Molecules in Crosslinked Dense Polymer Networks
Baicheng Mei, Tsai-Wei Lin, Grant S. Sheridan +3
The diffusion of molecules (penetrants) of variable size, shape, and chemistry through dense crosslinked polymer networks is a fundamental scientific problem that is broadly releva…
Dynamics and Rheology of Ring-Linear Blend Semidilute Solutions in Extensional Flow: Single Molecule Experiments
Yuecheng Zhou, Charles D. Young, Kathryn E. Regan +7
Ring polymers exhibit unique flow properties due to their closed chain topology. Despite recent progress, we have not yet achieved a full understanding of the nonequilibrium flow b…
Dynamics and Rheology of Ring-Linear Blend Semidilute Solutions in Extensional Flow: Modeling and Molecular Simulations
Charles D. Young, Yuecheng Zhou, Charles M. Schroeder +1
We use Brownian dynamics (BD) simulations and single molecule experiments to investigate the influence of topological constraints and hydrodynamic interactions on the dynamics and…
Simulation of semidilute polymer solutions in planar extensional via conformationally averaged Brownian noise
Charles D. Young, Charles E. Sing
The interplay between concentration, flow, hydrodynamic interactions (HI), and topological interactions governing semidilute polymer dynamics in strong flows are challenging to cha…
Conformational dynamics and internal friction in homo-polymer globules: equilibrium vs. non-equilibrium simulations
Thomas R. Einert, Charles E. Sing, Alfredo Alexander-Katz +1
We study the conformational dynamics within homo-polymer globules by solvent-implicit Brownian dynamics simulations. A strong dependence of the internal chain dynamics on the Lenna…
Non-monotonic hydrodynamic lift force on highly-extended polymers near surfaces
Charles E Sing, Alfredo Alexander-Katz
The hydrodynamic lift force that polymers experience near boundaries is known to be a crucial element when considering rheological flows of dilute polymer solutions. Here we develo…
