- •
Measurement of mixed gas self-diffusion in ZIF-polymer MMM by C-13 PFG NMR.
- •
Relationship between self-diffusion of mixed and pure gases in the MMM is quantified.
- •
Intra-ZIF diffusivity is smaller in the MMM than in the unconfined ZIF.
- •
Intra-polymer diffusivity is smaller in the MMM than in the neat polymer.
