Abstract: The invention provides improved hollow fiber membranes having at least two layers, and methods for forming the same. The methods include co-extruding a first composition, a second composition, and a third composition to form a dual layer hollow fiber membrane. The first composition includes a glassy polymer; the second composition includes a polysiloxane; and the third composition includes a bore fluid. The dual layer hollow fiber membranes include a first layer and a second layer, the first layer being a porous layer which includes the glassy polymer of the first composition, and the second layer being a polysiloxane layer which includes the polysiloxane of the second composition.

Abstract: The disclosure relates generally to a gas separation membrane and a gas separation method in which at least one type of gas is separated and recovered from a gas mixture, using the gas separation membrane. The gas separation membrane is asymmetric and hollow and made of a polyimide material. The method of the invention provides a practical, high-performance technique for gas separation.
