HIGH PERMEABILITY OXYGEN SEPARATION MEMBRANE COATED WITH ELECTROACTIVE LAYER ON BOTH SIDES AND FABRICATION METHOD THEREOF

摘要

The present disclosure discloses an oxygen separation membrane with high permeability coated with electroactive materials on both sides thereof in which electronic conductive materials and ionic conductive materials are mixed in an optimal ratio whereby the oxygen separation membrane according to the present disclosure has high oxygen permeability and a good thermal stability. Further the present membrane can be advantageously prepared using a simple process such as Tape casting and using a simple sintering process.
