On the Nature of Freezing/Melting Water in Ionic Polysulfones
Britannia Vondrasek, Chengyuan Wen, Shengfeng Cheng +2
We investigate the behavior of hydrated sulfonated polysulfones over a range of ion contents through differential scanning calorimetry (DSC), Fourier transform infrared spectroscop…
Hydration, Ion Distribution, and Ionic Network Formation in Sulfonated Poly(arylene ether sulfones)
Britannia Vondrasek, Chengyuan Wen, Shengfeng Cheng +2
We use molecular dynamics simulations to probe hydration, ion spacing, and cation-anion interaction in two sulfonated polysulfones with different ion distributions along the polyme…
Coarse-Grained Molecular Dynamics Modeling of A Branched Polyetherimide
Chengyuan Wen, Roy Odle, Shengfeng Cheng
A coarse-grained model is developed to allow large-scale molecular dynamics (MD) simulations of a branched polyetherimide derived from two backbone monomers [4,4'-bisphenol A dianh…
Determination of Glass Transition Temperature of Polyimides from Atomistic Molecular Dynamics Simulations and Machine-Learning Algorithms
Chengyuan Wen, Binghan Liu, Josh Wolfgang +3
Glass transition temperature () plays an important role in controlling the mechanical and thermal properties of a polymer. Polyimides are an important category of pol…
Insights into Hydration Dynamics and Cooperative Interactions in Glycerol-Water Mixtures by Terahertz Dielectric Spectroscopy
Ali Charkhesht, Djamila Lou, Ben Sindle +3
We report relaxation dynamics of glycerol-water mixtures as probed by megahertz-to-terahertz dielectric spectroscopy in a frequency range from 50 MHz to 0.5 THz at room temperature…
