- •
Mixed-linker ZIF synthesis allows control over porosity and pore size distribution.
- •
The mixed-linker ZIFs were used to fabricate composite membranes with Matrimid®.
- •
Composite membranes showed improved selectivity with increasing linker substitution.
- •
This behavior is due to higher effective diffusion selectivity in mixed-linker ZIFs.
- •
Higher CO2 permeability, permselectivity, and plasticization resistance were observed.
