Abstract: An artificial surface is disclosed where super-repellency is obtained solely from surface roughness regardless of the material's intrinsic wettability. The surface is able to repel all known liquids. The surface contains thereon a plurality of microstructures having a doubly re-entrant topology and a liquid-solid contact fraction of less than 50%. In one embodiment, the doubly re-entrant topology includes a cap portion and downwardly extending lip extending from the periphery of the cap portion. The surface withstands high temperatures and resists surface changing phenomenon such as biofouling and chemical scaling.
