Highly flexible, TpPa-1@PBI-BuI and TpBD@PBI-BuI hybrid membranes based on chemically stable covalent organic frameworks (COFs) could be obtained with the polymer. The loading obtained was substantially higher (50 %) than generally observed with MOFs. These hybrid membranes show an exciting enhancement in permeability (about sevenfold) with appreciable separation factors for CO2/N2 and CO2/CH4. Further, we found that with COF pore modulation, the gas permeability can be systematically enhanced.
基于化学稳定的共价有机框架（COF），可以与聚合物一起获得高度灵活的TpPa-1@PBI-BuI和TpBD@PBI-BuI混合膜。所获得的负载量（50%）比通常在金属有机框架（MOF）中观察到的要高得多。这些混合膜在渗透率方面有令人兴奋的提高（约七倍），对CO2/N2和CO2/CH4具有可观的分离因子。此外，我们发现通过COF孔调制，可以系统地提高气体渗透率。
