We’ve seen lots of hydrophobic materials before, but these water- and liquid-repelling materials often work within constraints. Some liquids bounce or wick away, while others--based on properties like viscosity or surface tension, or whether the substance in questions is organic or inorganic--are not affected by the hydrophobic qualities of the material. But a team of University of Michigan materials science is reporting a breakthrough that could have big implications for everything from stain-free clothing to protective surface coatings and chemical resistant protective suits: a superomniphobic coating that is resistant to pretty much any liquid we know of.
