Abstract
A durable superomniphobic device is presented where the polymeric device has a surface that includes doubly re-entrant micropillars residing within pockets that are partitioned within a matrix of interconnected doubly re-entrant walls. The doubly re-entrant matrix can be in a pattern where walls that are equal to or greater in height to the micropillars intersect or otherwise contact to provide protection to the more fragile micropillars. These durable superomniphobic devices can be formed by injection molding and can repel liquids having a surface tension of about 18 to about 98 mN mand display liquid contact angle of greater than or equal to 150°.
