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 lab 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.
