A polymeric membrane system containing a polymeric membrane and a substrate with interstitial gaps. Polymeric membrane components reside within the interstitial gaps of the substrate and below the surface of the substrate. Also, the layer of polymeric membrane components is thinner than the cross-sectional thickness of the substrate.
