- •
A facile method for simultaneously improving the permeance and selectivity is suggested.
- •
Mixed matrix membranes was developed using commercially available MgCO3 microcrystals.
- •
Amphiphilic comb polymer (CP) was an effective matrix due to specific interactions.
- •
High CO2/N2 selectivity of 93.8 and CO2 permeance of 30.9 GPU were obtained.
- •
Improved performance resulted from the enhanced CO2 solubility by MgCO3 crystals.
