Tailoring Copper Pillars to Prevent Physical Aging in Matrimid® 5218 Carbon Molecular Sieve Membranes
5218 CMSMs from this work showed no decline in permeability or selectivity for methane (107 Barrer) and carbon dioxide (1785 Barrer) over a period of 21 d. The results suggest that tailored metal pillars can suppress physical aging in CMSMs, thereby enhancing their long-term stability and applicability in gas separations.
