Title: Solidifiable composition for preparaton of liquid-infused slippery surfaces and methods of applying

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.
