Abstract
This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.
Claims12
A material comprising a substrate, at least one nanoparticle layer on at least a portion of the substrate and at least one omniphobic molecular layer on the nanoparticle layer, wherein the material comprises microstructures and nanostructures and the microstructures are provided from wrinkling a surface of the substrate and the nanostructures are provided from the at least one nanoparticle layer, and the portion of the substrate comprising the at least one nanoparticle layer and at least one omniphobic molecular layer form hierarchical structures that are omniphobic.
