Abstract

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.
