Graphene oxide (GO) is widely used to prepare 2D laminar separation membranes because of its single atomic thickness and good processability. However, due the tortuous transport path excessive swelling effect, it difficult improve permeability, salt rejection, stability GO simultaneously. Herein, we chemically laminated with covalent organic framework nanosheets (CONs) fabricate for fast stable desalination. CONs are first vacuum-filtrated then heated, obtaining bonded GO/CON (c-GO/CON) membranes. provide additional short pathways through intrinsic in-plane pores stabilize interlayer channels by forming cross-linked networks GO. As a result, rapid transmembrane water permeation improved desalination performances achieved. Moreover, prepared c-GO/CON show excellent stabilities in filtration processes complex environments, such as acidic basic conditions, elevated pressures, concentrated salinities, long-term operations. This study provides new idea preparation high-performance graphene-based nanofiltration
