A non‐fluorinated polythiophene film with dual superhydrophobic and superoleophilic wetting properties involving 2D assembly of polystyrene (PS) latex particles and electropolymerization is demonstrated. The phenomenon is stable at a wide range of temperatures and pH. It is easily and rapidly reversed with voltage or surfactant coincident with electrochromism.
