Abstract
gas separation membranes comprise a polymer membrane and an ozone reacting component, such as an antioxidant. The antioxidant may be included in the support layer of a composite membrane or included in the entire structure of an asymmetric membrane. The antioxidants in the separation membrane reduce oxidation and deterioration of the actual separation layer of the membrane.
