“Self-lubricating Organogels : SLUGs”, artificially mimicking slugs, were successfully prepared via a simple crosslinking of polydimethylsiloxane (PDMS) in the presence of several organic liquids.1,2 Due to the syneresis of the organogels, a thin liquid layer was continuously formed on the topmost of SLUG surfaces, under appropriate conditions. The resulting surfaces showed unusual dynamic dewetting behavior against various viscous emulsions, regeneration of superhydrophobicity, and thermo-responsive anti-icing properties. On our SLUG surfaces, even gecko cannot hold himself and slides off. It was also shown that geckos, whose feet have excellent adhesive properties, would slide off when placed on the SLUG surfaces.
