Abstract: Significance Tremendous amounts of organic solvents are used in industry, requiring chemical-resistant membranes for energy-efficient solvent recovery. Currently, organic solvent nanofiltration (OSN) is hindered by the instability of membranes in operation, in particular under high temperatures and in harsh solvents. In this research, we revealed the solvent transport across nanopores of single-layer graphene via molecular dynamics simulation and combined it with a resistance model to guide the design of a defect-tolerant graphene composite membrane for OSN. The graphene-covered membrane demonstrated high permeance and excellent resistance to DMF at high temperatures, offering possibilities for challenging separations.
