Abstract
AbstractThe fluorinated‐liquid infused amphiphobic slippery interfaces exhibiting superior sliding of the beaded oil/water droplets, often suffer from durability and contamination issues. Here, the ability of 1) hexagonal packing of hydrocarbon sides in a selected “comb‐like” polymer and 2) its reversible phase transition at 51 °C was rationally exploited to achieve temperature‐assisted rapid (<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, hydrophilic and thick (≈4.8 μm) polymeric coating. The resultant solid and smooth interface exhibited sliding of beaded droplets of various liquids, including droplets of water, polar (ethanol, 1‐propanol, 1‐hexanol, DMSO, DMF), and non‐polar (decane, dodecane, diiodomethane) organic solvents, edible (vegetable oil), motor, engine (petrol, diesel, kerosene) and crude oils.
