On‐again, off‐again personality : Superhydrophobic conducting polypyrrole (PPy) films are synthesized through a facile electrochemical process. The PPy films exhibit an extended porous structure with both coarse‐ and fine‐scale roughness (see image). By controlling the electrical potential, PPy films can be switched between the oxidized state and the neutral state, resulting in reversibly switchable superhydrophobic and superhydrophilic properties.
