Vacuum-driven nanofiltration (NF) is a promising and low-cost alternative to pressure driven NF but existing commercial membranes currently not achieve any relevant water flux in such a system. Here, the authors fabricate a silk-based membrane with a crumpled and defect-free rejection layer, showing high flux and salt rejection rate under cross-flow filtration mode.
