Abstract: 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 anchoring molecules, where each anchoring molecule has a head group that is covalently linked to the surface and a functional tail group. The anchoring molecules are crosslinked to each other to form a crosslinked network. The functional tail group has an affinity for a lubricating liquid, which is applied to the treated surface to form a lubricating layer. The anchoring layer and replenishable lubricating liquid 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.
