Welcome to the home page of the Patton Research Group!! Research in the Patton Group is centered on the design of new polymeric materials.  We are particularly interested in the design of functional polymer surfaces and thin films with applications ranging from antifouling coatings to fuel cell membranes.  Our work environment is team-oriented and  interdisciplinary bringing together scientists with expertise in polymer synthesis, surface chemistry, thin film fabrication, and surface analytical techniques for the design of functional polymer surfaces.

Simple Approach to Robust Superhydrophobic Coatings

We reported a simple and versatile method for the fabrication of superhydrophobic inorganic-organic thiol-ene coatings via sequential spray-deposition and photopolymerization under ambient conditions.  The coatings are obtained by spray-deposition of UV-curable hybrid inorganic-organic thiol-ene resin. The spray-deposition process and nanoparticle agglomeration/dispersion provide surfaces with hierarchical morphologies exhibiting both micro- and nanoscale roughness. The wetting behavior can be varied over a broad range to ultimately provide coatings with high static water contact angles (> 150), low contact angle hysteresis, and low roll off angles (< 5).  The crosslinked thiol-ene coatings are solvent resistant, stable at low and high pH, and maintain superhydrophobic wetting behavior after extended exposure to elevated temperatures.  We demonstrate the versatility of the spray-deposition and UV-cure process on a variety of substrate surfaces including glass, paper, stone, and cotton fabric.
