Self-lubricating surfaces for food packaging and food processing equipment

摘要

An article having a liquid-impregnated surface. The surface includes a matrix of solid features (124) (e.g., non-toxic and/or edible features) spaced sufficiently close to stably contain a liquid (126) therebetween or therewithin, wherein the liquid is non-toxic and/or edible. The article may contain, for example, a food or other consumer product, such as ketchup, mustard, or mayonnaise. The resulting article is water repellent, providing less viscous drag.
