Abstract:
A coating that can be easily applied, clear, well-bonded, and superhydrophobic is disclosed. In one aspect, a method for coating a substrate comprises providing a substrate having a surface, disposing a coating composition adjacent the surface, the composition comprising a hydrophobic fluorinated solvent, a binder comprising a hydrophobic fluorinated polymer, and hydrophobic fumed silica nanoparticles. Also disclosed is an article comprising a coating layer, the coating layer comprising a plurality of nanoparticles partially exposed on an outward surface thereof.
