Nonstick : Dynamically oleophobic surfaces have been produced from low‐molecular‐weight poly(dimethylsiloxane) (PDMS) brush films. Despite the statically oleophilic nature of these nonroughened, nonperfluorinated surfaces, ultralow tilt angles (TAs) that set drops of various nonpolar liquids in motion were achieved. Heating the surfaces enhances droplet mobility by significantly reducing the TAs (see scheme; CA=contact angle).
