Pursuing high water permeance with ultrahigh selectivity is a longstanding objective for nanofiltration membranes. At present, simultaneously engineering an ultrathin thickness and loose architecture of nanofiltration membranes is in great demand and a severe challenge. Herein, we demonstrate a two-...
