Abstract:
An anti-fouling coating is provided, containing a continuous matrix comprising a first component; a plurality of inclusions comprising a second component, wherein the first component is a low-surface-energy polymer having a surface energy, and the second component is a hygroscopic material containing one or more ionic species. The low-surface-energy polymer and the hygroscopic material are chemically connected ionically or covalently, such as in a segmented copolymer composition comprising fluoropolymer soft segments and ionic species contained within the soft segments. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. Coefficient-of-friction experimental data is presented for various sample coatings. The incorporation of ionic species into the polymer chain backbone increases the hygroscopic behavior of the overall structure. Improvement in lubrication enables material to be cleared from a surface using the natural motion of an automotive or aerospace vehicle.
