Abstract
Disclosed are polymeric blend membranes, and methods for their use, that include a blend of at least a first polymer and a second polymer, wherein the first and second polymers are each selected from a polymer of intrinsic microporosity (PIM), a polyetherimide (PEI) polymer, a polyimide (PI) polymer, or a polyetherimide-siloxane (PEI-Si) polymer, and wherein the polymeric membranes have been both ultraviolet (UV)-treated and thermally-treated.
