METHODS AND FORMULATIONS FOR SUPERHYDROPHIC, SELF-CLEANING, AND ICEPHOBIC POLYMER COATINGS AND OBJECTS HAVING COATINGS THEREON

摘要

An object has a superhydrophic, self-cleaning, and icephohic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of microstructuring microparticles, liquid silane having one or more groups configured to graft to a microstructuring microparticle and at least another group that results in hydrophobicity. The microstructuring microparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting adhesives, 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.
