Abstract: A body having a lubricant reservoir is described, comprising: a porous polymeric body; and a lubricating liquid, said lubricating liquid occupying the pores to provide a lubricated porous surface having a lubricant reservoir and a lubricant overlayer over the polymer surface. Also described herein is a system for use in the formation of a low-adhesion and low-friction surface includes a flowable precursor composition comprising a prepolymer and a curing agent, said composition capable of application as a coating over a large surface area; a lubricating liquid that is capable of forming a coating with the hardened precursor composition, wherein the lubricating liquid and hardened polymer together form a coating of lubricating liquid stabilized on and in the hardened polymer; and instructions for applying the precursor composition onto a surface for the purpose of obtaining a low-adhesion and low-friction surface.

Abstract: Methods and compositions disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. An article having a repellant surface includes a substrate comprising fabric material and a lubricant wetting and adhering to the fabric material to form a stabilized liquid overlayer, wherein the stabilized liquid overlayer covers the fabric material at a thickness sufficient to form a liquid upper surface above the fabric material, wherein the fabric material is chemically functionalized to enhance chemical affinity with the lubricant such that the lubricant is substantially immobilized on the fabric material to form a repellant surface.
