Abstract

original image

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.
