A reverse method involves the pre-formation of an Matrimid (MI)-selective layer, followed by a porous polysulfone (PSF) support deposition. The membrane exhibited a high H 2 /CH 4 selectivity and a moderate H 2 permeance. This study introduces a facile method to produce membranes with inexpensive materials.
