In the present work we report a simple ‘dip-coating’ process that imbues oleophobicity to various surfaces that inherently possess re-entrant texture, such as commercially available fabrics, as shown in the following figure. We also show that such dip-coated fabric surfaces exhibit, reversible, deformation-dependent, tunable wettability, including the capacity to switch their surface wetting properties (between super-repellent and super-wetting) against a wide range of polar and non-polar liquids.
