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.
