ABSTRACT

ABSTRACT

A novel composite membrane consisting of an interconnected MOF scaffold coated with cross-linked poly(ethylene glycol) (PEG) has been developed. As a result of its unique structure, the membrane shows an exceptional 18-fold permeability enhancement as compared to pristine PEG membranes, without compromising the selectivity. This performance is unattainable with current mixed-matrix membranes (MMMs). Our optimized membrane has a permeability of 2700âBarrer with a CO2 /N2 selectivity of 35, which surpasses the latest Robeson upper bound.
