Facile Creation of a Super‐Amphiphobic Coating Surface with Bionic Microstructure

A super‐amphiphobic polymeric coating , i.e., one that shows both water‐ and oil‐repellent properties, produced by a simple, one‐step casting process from two common polymers, is described. The micro–nano binary structure of the film has similarities to that of a lotus leaf. The Figure shows a water droplet on the coating surface, demonstrating a contact angle (CA) of 166 °C.
