Hierarchically Structured Superoleophobic Surfaces with Ultralow Contact Angle Hysteresis

Year: 2012

Type: article

Abstract: 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°.
