Superomniphobic surfaces, which repel a wide range of liquids, have gained significant attention for their potential in various industrial and biomedical applications. Traditionally, these surfaces have been made using perfluorocarbon coatings, raising environmental and health concerns. Our research presents a simple method to create flexible superomniphobic surfaces without perfluorocarbon coatings. Inspired by the skin of springtails, we developed mushroom-like micropillars with downward-facing edges using a micromolding technique. The shape of these mushroom caps can be adjusted by depositing a thin aluminum layer, causing them to bend and form a doubly re-entrant structure. These surfaces effectively repel low-surface-tension liquids like oils, alcohols, and fluorinated solvents. Remarkably, the superomniphobic properties are maintained even under mechanical stretching and after surface energy modifications. This innovation has potential applications in self-cleaning clothes and gloves, among others. – Scientific Journal cover design by scapiens
