Wet, wetter, wettest : The surface wettability of copper films can be controlled between superhydrophobicity and superhydrophilicity by micro‐ and nanoscale hierarchical structures and self‐assembled monolayers of alkanoic acids. The picture shows the shapes of water droplets on films prepared with different acids and the contact angle as a function of acid chain length.
