1. A liquid-coated substrate, comprising:
a substrate having a spatially heterogeneous surface pattern, said spatially heterogeneous pattern comprising:
at least one first region having surface characteristics that provide a stable liquid film with a first lubricating liquid; andat least one second region having one of surface characteristics that provide an unstable liquid film with said first lubricating liquid or apertures or holes that provide liquid conduits through the substrate; and a first lubricating liquid disposed over at least a portion of said first region to provide an immobilized liquid layer.
