Amphiphobic slippery interfaces infused with fluorinated liquid often suffer from durability and contamination issues due to the leaching of environmentally non-viable lubricant. As a promising alternative, recently, some non-fluorinated and optically transparent solid-slippery interfaces have been introduced. However, the reports of scalable, non-fluorinated, substrate independent, and self-healable amphiphobic solid-slippery coating that allow the sliding of refined/crude oils along with polar and non-polar solvents are extremely rare. In this work, we have shown a non-fluorinated, substrate-independent, and self-healable amphiphobic solid slippery coating following a simple and scalable fabrication process. Hexagonal packing of hydrocarbon sides in a selected ‘comb-like’ polymer polyoctadecylacrylate (PODAc) and its reversible phase transition at 51°C was rationally exploited to achieve temperature-assisted rapid (&lt; 1 minute) and repetitive (50 times) self-healable amphiphobic solid-slippery coating on both planar and geometrically-complex substrates. The selected ‘comb-like’ polymer was strategically infused in a porous and thick (~ 4.8 μm) polymeric coating derived through a 1,4-conjugate addition reaction between amine and acrylate. The resultant solid and smooth interface exhibited the sliding of various beaded liquids with a wide range of surface tensions (72 mN/m to 21.5 mN/m).
