Rapid development of thickness‐controllable superamphiphobic coating on the inner wall of long narrow pipes

A novel electrochemical technique had been introduced to prepare nanocrystalline superamphiphobic coatings inside of narrow pipes of significant length. The axially propagated ultrasound was utilized to ensure the scaling‐up potential of this technique. The coating had strong mechanical strength, durability in low/high pH solutions and the potential of controlling its thickness while preserving a stable nonwetting performance. In addition, the properties of anti‐scaling and drag reduction under the flowing circumstance had been demonstrated. © 2017 American Institute of Chemical Engineers AIChE J , 63: 3636–3641, 2017
