Nanostructured graphitelike carbon films are prepared through a simple pyrolysis method. The as‐prepared films are superhydrophobic for not only pure water but also corrosive liquids, such as acidic and basic solutions. The picture shows water droplets with pH values of 1.07 (left) and 13.76 (right) in contact with a nanostructured carbon film. This is the first example of superhydrophobicity over the whole range of pH values, without the presence of fluorine‐containing compounds.
