The salts and ions for the synthesis process were purchased as they are named and listed in the article. The polymer films were fabricated using NIPS method. The fabricated MMM were tested with different classical tests (XRD, FTIR, XPS, SEM, 3D Scan, TEM) and gas permeation method. ______Methods of data collection______ *More detailed description can be found in article: Ashtiani, S.; Wu, B.; Khoshnamvand, M.; Schneider, J.; Floreková, J.; Regner, J.; Chauhan, P.; Sofer, Z.; Friess, K.

The temperature (25 °C) was controlled using a heating unit (Bravo B 4273) and cooling system (Julabo F250). Experiments were conducted at pressures ranging from 0.1 to 0.5 MPa and 1 MPa, with 30–55 mg samples sealed in glass tubes and evacuated (
