Polycationic Polymer-Regulated Assembling of 2D MOF Nanosheets for High-Performance Nanofiltration

(2-fold higher than its pristine) and excellent rejection rates (over 90%) for organic dye with size larger than 0.8 × 1.1 nm. This permeance value is about 2 orders of magnitude higher than the commercial polymeric NF membrane. Additionally, the membranes demonstrate 20-40% salt rejection.
