The H2/CO2 separation properties of di/triamine vapor cross‐linked mixed matrix membranes with molecularly tuned free‐volume at 150 °C are reported. Free‐volume is molecularly tuned by altering the degree of chain‐motion using cross‐linkers with different chain lengths. A more restricted degree of c...
