Nanotexturing to produce surfaces containing hydrophobic functionality was demonstrated with the production of plasma etched silicon (black silicon, bSi), chemically etched copper (black copper, bCu), and nano-wrinkled metal films formed on thermally relaxed, or shrunken plastic sheets. The features common to all of these surfaces high surface area, a surface structure resulting from self-organization and are surfaces that can be coated by metallic films using sputtering techniques. Such surfaces are applicable for sensor applications. The potential for applying these surfaces in anti-biofouling and hydrophobic applications is discussed.
