King, William P. Torrealba, Eduardo 2013-08-22T16:48:16Z 2013-08-22T16:48:16Z 2015-08-22T10:00:25Z 2013-08 2013-08-22T16:48:16Z 2013-08 This thesis reports changes in apparent contact angles for droplets of various liquids on microstructured surfaces in saturated environments. Micro scale pillar surfaces maintain the non-wetting Cassie-Baxter regime for drops of water over a range of saturation temperatures while micro scale waffles transition into a partially wetted state under the same conditions. Micro scale mushroom and waffle surfaces are able to maintain oleophobic behavior for droplets in a saturated environment with a concentration of up to 50% R-134a. The surfaces described in this thesis could be used to significantly improve devices that rely upon a liquid-vapor interface, including two-phase heat exchangers, water purification systems, and microfluidic devices.
