Advanced, Liquid-Repellent Nanoscale Coating

University of Michigan engineering researchers have developed a nanoscale coating that is at least 95 percent air, and repels the broadest range of liquids of any material in its class. Direct applications include breathable garments to protect soldiers and scientists from chemicals, and fingerprint-resistant surfaces for electronic devices like phones and tablets. In a demonstration, the surface repelled coffee, soy sauce, and vegetable oil, as well as toxic hydrochloric and sulfuric acids that could burn skin.
