Covalent triazine unit-based negatively charged conjugated microporous polymer membranes and methods of making the same
By designing a specific synthetic route and stepwise polymerization process for negatively charged cyanophenyl monomers, and combining heating for film formation with quenching in pure water for fixation, the problems of single function and poor film stability of covalent triazine polymer membranes were solved. High-performance covalent triazine unit-based negatively charged conjugated microporous polymer membranes were prepared, achieving excellent gas separation performance.

AI Technical Summary
Traditional covalent triazine polymers have limited functionality, poor film stability, and insufficient separation performance. Existing film formation processes lack efficient shaping methods and systematic post-processing procedures, resulting in poor film structure stability and inadequate separation performance.
A covalently triazine-based conjugated microporous polymer membrane was prepared by using a synthetic route of negatively charged cyanophenyl monomers, a stepwise polymerization process, a post-treatment process of heating to form a film, quenching in pure water for setting, and immersion in two solvents.
We have achieved efficient preparation of covalent triazine unit-based conjugated microporous polymer membranes with excellent structure and performance, which exhibit high selectivity and high permeability in gas separation, thereby improving membrane stability and separation efficiency.
