Abstract

A porous membrane patterning technique is provided. In one embodiment, a porous membrane may be patterned via printing on the porous membrane with a solvent such that the porous membrane collapses where the solvent is applied. In another embodiment, a patterned porous membrane may be formed by casting a solution including at least components of the porous membrane into voids of a casting plate or stencil, removing the casting plate, and letting the remaining components go through a phase inversion process to form porous membrane regions.
