Making Materials That Repel All Liquids

Making Materials That Repel All Liquids 

 Water (dyed blue) and hexadecane (dyed red), an oil, bead up on an omniphobic surface, which repels all liquids.

Materials under development at MIT could lead to coatings that repel both water and oil. A group of MIT researchers have created an improved set of design rules for making any surface impervious to any liquid, be it water or gasoline. Such materials could eventually have promise as fingerprint-repelling coatings, fuel filters, self-washing car paints, and stain-resistant clothing.
