Abstract

See full text

An object has a durable superhydrophic, self-cleaning, and icephobic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of hierarchical structuring micro/nanoparticles, liquid silane having one or more groups configured to graft to a hierarchical structuring micro/nanoparticle and at least another group that results in hydrophobicity. The hierarchical structuring micro/nanoparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting binders, moisture curing adhesives or polymers that form a strong interaction with a surface, is in solution with a solvent. Upon curing, the layer has a contact angle greater than 90° and a sliding angle of less than 10° and, less than 5% of an area of the layer is removed in a Tape test.
