Fully reversible transition from Wenzel to Cassie-Baxter states on corrugated superhydrophobic surfaces.
This paper reports on a new, simple design paradigm consisting of parallel grooves with an appropriate aspect ratio that allows for the controlled, reversible switching between the Cassie-Baxter and Wenzel wetting states with an electrical field, The work is supported by theory and of great significance for a wide variety of applications in microfluidic devices and displays. It involved an international collaboration with Oxford University, Max Planck Institute (Potsdam), University J. Fourier (Grenoble) and Philips Research Laboratories in the Netherlands.
