A Coating that Really Doesn't Like Water
A transparent coating that isn't just impermeable to water but actually
makes it bounce off a surface has a number of potentially interesting applications.
It could prevent corrosion, protect electronics and antiquities, or provide
a new, more efficient surface to collect pure water. Modeled from Nature, the
Brinker group used sol-gel chemistry to make a patent-applied-for, simple-to-prepare
coating solution that, upon simple drying, develops a nanoscopically rough silicon
dioxide surface decorated with hydrophobic (water-hating) ligands.
