Thickness dependent penetrant gas transport properties and separation performance within ultrathin polysulfone membrane: Insights from atomistic molecular simulation

Simulation technique has been employed to elucidate the effect of thickness upon confinement to gas transport properties in pure and binary mixtures within ultrathin polysulfone membranes. It is found that the gas diffusivity, solubility, and permeability are improved with increment in membrane thic...
