Room-temperature endogenous lubricant-infused slippery surfaces by evaporation induced phase separation

We present a novel approach to fabricate endogenous slippery lubricant-infused porous surfaces (eSLIPS) at room temperature using an evaporation-induced phase separation process. The ternary coating system, comprising ethylene-propylene copolymer, caprylyl methicone, and n-hexane, forms a porous structure in situ infiltrated with lubricant, resulting in surfaces with remarkable anti-fouling and anti-icing properties. Endogenous slippery lubricant-infused porous surfaces with excellent anti-icing properties are fabricated by one-step evaporation-induced phase separation.
