Implication

Fabrication method achieves tunable microstructure and high porosity in covalent organic framework membranes, indicating potential for molecular separation.

Key Points

The new method enables scalable fabrication of covalent organic framework membranes with tunable microstructure.
Membranes exhibit high mechanical strength with ultimate tensile strength up to 60 MPa, demonstrating robustness.
The COF membranes achieve over 99% rejection in nanofiltration of aqueous dye solutions, showing excellent separation performance.
Heating conditions can finely tune morphology, porosity, and crystallinity, enhancing membrane functionality.
