Summary: Traditional technologies for solvent/water separation are energy intensive, but state-of-the-art organic solvent nanofiltration (OSN) membranes have limited solvents discrimination ability. This study used a pressure-assisted cross-linking strategy to coat graphene oxide (GO) on hollow fiber membranes, resulting in improved stability in solvent environments. The GO layer exhibited rapid transport of acetonitrile while impeding water penetration, and the cross-linked GO hollow fiber (CGHF) membrane showed high acetonitrile permeance and the ability to concentrate dilute acetonitrile solutions. This research provides a promising prospect for energy-efficient solvent dehydration and OSN.
