Temporal fluctuations of non-equilibrium water accessible pathways in polyamide reverse osmosis active layers
Molecular-scale simulations of pressure-driven transport through polyamide domains were performed. Analysis revealed the importance of non-equilibrium molecular distributions and the existence of connected pathways from feed to permeate at all times. Individual pathways were found to be ephemeral with an observed upper bound persistence time of 1.75 ns.
