Hierarchically structured, superoleophobic surfaces displaying one of the lowest contact angle hysteresis ever reported are developed by Anish Tuteja and co‐workers on page 5838. These surfaces allow droplets of the extremely low surface tension liquid, n‐heptane, to bounce and roll off at tilt angles ≤ 2°.
Hierarchically structured, superoleophobic surfaces are demonstrated that display one of the lowest contact angle hysteresis values ever reported – even with extremely low‐surface‐tension liquids such as n‐heptane. Consequently, these surfaces allow, for the first time, even ≈2 μL n‐heptane droplets to bounce and roll‐off at tilt angles. ≤ 2°.
