Rethinking the Transient Network Concept in Entangled Polymer Rheology
Wen-Sheng Xu, Christopher N. Lam, Jan-Michael Y. Carrillo +2
The classical rheological theories of entangled polymeric liquids are built upon two pillars: Gaussian statistics of entanglement strands and the assumption that the stress arises…
Influence of Side Chain Isomerism on the Rigidity of Poly(3-alkylthiophenes) in Solutions Revealed by Neutron Scattering
William D. Hong, Christopher N. Lam, Yangyang Wang +5
Using small angle neutron scattering, we conducted a detailed structural study of poly(3-alkylthiophenes) dispersed in deuterated dicholorbenzene. The focus was placed on addressin…
Comment on: "Relating Chain Conformations to Extensional Stress in Entangled Polymer Melts"
Wen-Sheng Xu, Christopher N. Lam, Jan-Michael Y. Carrillo +2
Based on non-equilibrium molecular dynamics simulations of entangled polymer melts, a recent Letter [Phys. Rev. Lett. , 047801 (2018), arXiv:1806.09509] claims that t…
Scaling Behavior of Anisotropy Relaxation in Deformed Polymers
Christopher N. Lam, Wen-Sheng Xu, Wei-Ren Chen +12
Drawing an analogy to the paradigm of quasi-elastic neutron scattering, we present a general approach for quantitatively investigating the spatiotemporal dependence of structural a…
