New Coating Causes Liquids To Bounce Off Any Surface
The ‘superomniphobic’ liquid-repelling coating could make clothing stain-proof or make ships faster by reducing drag.
A team of researchers at the University of Michigan have developed a nanoscale coating that can be applied to any surface to repel liquids. The ‘superomniphobic’ coating is at least 95% air and causes liquids to bounce off the treated surface. To apply it, the researchers used electrospinning to create fine particles of solid from a liquid solution with an electric charge.
The coating is a mixture of rubbery plastic particles of “polydimethylsiloxane” and liquid-resisting nanoscale cubes developed by the Air Force that contain carbon, fluorine, silicon, and oxygen.
