Abstract

Porous composites comprise a porous membrane having a structure defining a plurality of pores extending therethrough, nonporous discontinuous surface layer affixed to said porous membrane, in which the nonporous discontinuous surface layer forms regions of gas permeability, and regions of gas impermeability, and a coating disposed upon the porous composite which renders at least a portion of the porous composite oleophobic.
