Abstract
A conductive superhydrophobic surface has been fabricated by a simple wetting chemical reaction, changing its wetting behaviour upon applying a very low external threshold voltage of about 0.3 V when the contact angle starts to decrease from superhydrophobic to hydrophobic. This will open up a variety of applications, such as the design of biosensors, lab-on-a-chip devices, and the controlled movement of micro-droplets with smart identification. A promising formation mechanism about electricity-driven wettability is also presented.
