Chemically Bonded Graphene Oxide/Covalent Organic Framework Nanosheets as Robust Membranes for Fast Desalination.

Graphene oxide (GO) is widely used to prepare 2D laminar separation membranes because of its single atomic thickness and good processability. However, due to the tortuous transport path and excessive swelling effect, it is difficult to improve permeability, salt rejection, and stability of GO membranes simultaneously. Herein, we chemically laminated GO with covalent organic framework nanosheets (CONs) to fabricate membranes for fast and stable desalination.
