An apparatus for enhancing the coalescence of a dispersed phase from a continuous phase in an emulsion is presented. The apparatus includes at least one inlet for receiving the emulsion, at least one outlet for discharging the emulsion after coalescing the dispersed phase, and at least one article disposed between the inlet and the outlet. The article includes a plurality of regions disposed on a surface in a predefined pattern, wherein a portion of the plurality of regions is substantially wetting with respect to the dispersed phase, and a portion of the plurality of regions is substantially non-wetting with respect to the dispersed phase, and wherein the pattern includes a plurality of inter-connected regions that are substantially non-wetting with respect to the dispersed phase. A related article is also presented.
