Generalized model for the diffusion of solvents in glassy polymers: From Fickian to super Case II
Jiayuan Miao, Mesfin Tsige, Philip L. Taylor
The diffusion of small solvent molecules in glassy polymers may take on a variety of different forms. Fickian, anomalous, Case II, and super Case II diffusion have all been observe…
Volume analysis of supercooled water under high pressure
Solomon F. Duki, Mesfin Tsige
Motivated by an experimental finding on the density of supercooled water at high pressure [O. Mishima, J. Chem. Phys. 133, 144503 (2010)] we performed atomistic molecular dynamics…
Interdiffusion of Solvent into Glassy Polymer Films: A Molecular Dynamics Study
Mesfin Tsige, Gary S. Grest
Large scale molecular dynamics and grand canonical Monte Carlo simulation techniques are used to study the behavior of the interdiffusion of a solvent into an entangled polymer mat…
Molecular Dynamics Simulation of Solvent-Polymer Interdiffusion. I. Fickian diffusion
Mesfin Tsige, Gary S. Grest
The interdiffusion of a solvent into a polymer melt has been studied using large scale molecular dynamics and Monte Carlo simulation techniques. The solvent concentration profile a…
