(a) Water droplets sliding down dry ULDPE films have a noticeable asymmetry in shape due to CAH (top), while there is no appreciable difference between the advancing and receding angles of droplets on oil-impregnated ULDPE (bottom). (b) The sliding angle of a 1.3 g dollop of ketchup is 23° on dry ULDPE (top images), but only 4° on oil-impregnated ULDPE (bottom). (c) On dry films (top images), sliding ketchup leaves behind considerably more residue than on infused films (bottom).
