The amine-rich COFs is incorporated into polyamide layer to prepare hybrid membranes. Efficient water channels are fabricated in membrane by incorporating the COFs. The covalent bonds between COFs and polymer is benefit for interface compatibility. The water flux increased distinctly while salt rejection changed slightly.
