Local ion environment in polyamide membranes revealed by molecular dynamics
Nathanael S. Schwindt, Anthony P. Straub, Michael F. Toney +1
In reverse osmosis (RO) and nanofiltration (NF) membranes, the polymer structure and interactions with solvent and solutes dictate the permeability and selectivity. However, these…
