Airy, stay-dry material

A superomniphobic material that is 95% air can repel most liquids, according to a study at the University of Michigan. Such a material might trivially be used to make stain-resistant fabrics but could have more vital applications as protective gear for scientists handling hazardous substances or military personnel under threat of chemical attack. The material might even be used to coat ships' hulls to reduce sea-faring drag as well as coating smart phone screens to prevent finger marks. The coating is an electrospun blend of polydimethylsiloxane and fluorodecyl polyhedral oligomeric silsequioxane.Virtually any liquid you throw on it bounces right off without wetting it, explains research leader Anish Tuteja.
