Abstract
A method is provided for attaching a membrane to a substrate by heat-bonding the membrane to the substrate. The substrate includes a top surface, a bottom surface and a receptacle therethrough. The membrane can be a porous support structure combined with a polymeric gel. The method includes the steps of inserting a mandrel into the receptacle, placing the membrane on the substrate across the receptacle, heating the membrane and substrate, and allowing the substrate to cool to provide heat-bonded interlock between the substrate and the membrane.
