Such surfaces may be found in the natural world and their potential applications range from waterproof and self-cleaning surfaces to droplet microfluidics. A measure of hydrophobicity is obtained from the angle between the liquid and solid surface measured from the solid through the liquid, known as the contact angle. Variations in this angle can indicate not only a level of ‘wetting’ of the surface but also small amounts of droplet movement and may be achieved by electrowetting, the application of a voltage between a liquid droplet and a substrate, and/or by varying the local topography of the surface. Photolithography and thin-film deposition fabrication techniques have been used to create hydrophobic and superhydrophobic surfaces for use in electrowetting experiments. Both AC and DC electrowetting behaviour has been investigated and the results have been shown to be in agreement with past work and well established theory.
