“Graphene oxide” coatings, a few tens of nanometers thick, can be reversibly buckled by stretching and releasing the substrate. This leads to a dramatic change in the surface topography with intricate flower‐like folding patterns with blisters and sharp folds, as described by J. Yin, A. H. Dyson, N. Koratkar, and co‐workers on page 3256. Such a topography is shown to be highly effective at scattering incident light with potential applications for dynamic glazing and switchable optics.
