The enrichment of air in O2 and N2 has many potential applications in many different fields (combustion, medicine, chemical synthesis). Polymer membranes are an economic and easy processing alternative to pure inorganic membranes. Although polymers are being developed to meet these demanding needs, their selectivity and permeability are still very low for a large-scale application. Mixed matrix membranes consist in the introduction of a inorganic filler of special properties in a polymer matrix, with the aim of obtaining a synergy of the properties of both: the easy processability of polymers and the molecular sieving effects of the filler.
