Objectives are proposed concerning the molecules that form self assembled monolayers SAMs that can be used in colloidal powder processing and the fabrication of textured, super-hydrophobic ceramic surfaces. The first objective is to understand and control the steric forces between particles coated with hydrophilic water loving SAMs. This approach is new and will be exploited by industry in a variety of applications. The second is to use this knowledge to produce ceramics with micron to submicron periodic surface features using elastomer molds that are produced by a new photolithographic methods. The third objective is to produce textured surfaces with hydrophobic water hating SAMs to produce super-hydrophobic surfaces wetting angles 165 degrees with unique features that include the biologically inspired self-cleaning properties of the lotus leaf, rain-repellent radomes with improved reliability during storms, surfaces designed to decrease the resistance to fluid flow drug delivery in MEMS devices, and surfaces that either restrict or encourage selective liquid condensation. Progress towards these and other goals have been reported in the 15 technical reports. Many of these have been published in refereed journals.
