Articles, methods of making, and uses for modifying surfaces for liquid repellency are disclosed. The liquid repellant surfaces comprise a surface comprising an anchoring layer. The anchoring layer, which forms an immobilized molecular anchoring layer on the surface, has a head group that is covalently linked to, or adsorbed onto, the surface and a functional group. The functional group of the treated surface has an affinity for a lubricating layer, which is applied to the treated surface. The anchoring layer and replenishable lubricating layer are held together by non-covalent attractive forces. Together, these layers form an ultra-repellant slippery surface that repels certain immiscible liquids and prevents adsorption, coagulation, and surface fouling by components contained within. |
