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.
