Session 3: Functional and Smart Coatings
Speaker(s):
W. Marshall Ming, Georgia Southern University
There has been substantial interest in developing superhydrophobic and superoleophobic surfaces in both academia and industry due to their potentially wide applications. The well-known self-cleaning property of the lotus leaf is due to a combination of proper chemistry and unique dual-scale surface topography. We have successfully mimicked the dual-scale structure either by incorporating nano-raspberry-like particles to polymer films or via layer-by-layer particle deposition, which have been turned superhydrophobic with very low water roll-off angles. We have further expanded our strategy to prepare robust water-borne superhydrophobic coatings by judiciously combining silicone-containing acrylic latexes made from emulsion polymerization with micro/nano-sized inorganic particles.
