AB  - Mixed matrix materials (MMMs) hold great potential for membrane gas separations 
      by merging nanofillers with unique nanostructures and polymers with excellent 
      processability. In situ growth of the nanofillers is adapted to mitigate 
      interfacial incompatibility to avoid the selectivity loss. Surprisingly, 
      functional polymers have not been exploited to co-grow the nanofillers for 
      membrane applications. Herein, in situ synergistic growth of crystalline zeolite 
      imidazole framework-8 (ZIF-8) in polybenzimidazole (PBI), creating highly porous 
      structures with high gas permeability, is demonstrated. More importantly, PBI 
      contains benzimidazole groups (similar to the precursor for ZIF-8, i.e., 
      2-methylimidazole) and induces the formation of amorphous ZIFs, enhancing 
      interfacial compatibility and creating highly size-discriminating bottlenecks. 
      For instance, the formation of 15 mass% ZIF-8 in PBI improves H(2) permeability 
      and H(2) /CO(2) selectivity by  approximately 100% at 35  degrees C, breaking the 
      permeability/selectivity tradeoff. This work unveils a new platform of MMMs 
      comprising functional polymer-incorporated amorphous ZIFs with hierarchical 
      nanostructures for various applications.
