Polymer and nanocomposite coatings play an important role in preventing corrosion, influencing wetting properties, and enabling purification in any process industry. Oil and water separation (emulsion breaking) including the use of solvent separation systems are important for any industrial process that requires filtration and separation of waste streams. In this talk, we will describe the used of nanostructured coatings for corrosion mitigation and their use in oil-water separations and filtrations. The use and characterization of polythiophenes, polbenzoxazines, and nanocomposite coatings is described. We also describe the use polymer aerogels capable of efficient solvent and oil/water separation. The nanostructuring mechanism during fabrication is based on hierarchical roughness and house-of- card interactions where the charges generated on the surface of the nanoplatelets compliments the chemistry that can be done on the surface, e.g. with silane agents. The interest is in utilizing the capabilities of these polymers and nanomaterials for non-fouling, anti-corrosion, selective super-wetting, and separation of immiscible liquids.
