Self‐healing corrosion protection is provided by functional polyoxometalate ionic liquids (POM‐ILs) coated onto metal surfaces. In their Communication on page 13596 ff., C. Streb et al. utilize POM‐ILs, which are hydrophobic, acid‐resistant, and form mechanically stable films, to protect copper metal against acid corrosion. Mechanical damage to the coating is self‐repaired in less than one minute through the unique rheological properties of the compounds.
