Creation of super-hydrophobic siloxane-modified SU-8 microstuctures

Recently, the need for super-repellent surfaces has been increasing, with applications ranging from material science to Lab-on-a-Chip diagnostics and microfluidics. We propose a novel and simple method to engineer super-hydrophobic surfaces using commercially available negative-tone resists, namely...

Description
Summary:Recently, the need for super-repellent surfaces has been increasing, with applications ranging from material science to Lab-on-a-Chip diagnostics and microfluidics. We propose a novel and simple method to engineer super-hydrophobic surfaces using commercially available negative-tone resists, namely SU-8 and the photodefinable spin-on silicone elastomer, PDSE. The surface energies of fabricated materials were investigated and applied to the transition from the super-hydrophobic to hydrophilic states, occurring during liquid phase evaporation.
