ResumoDual-stimuli-responsive surfaces are reported here that work under the external stimuli of temperature and/or pH, as demonstrated in the Figure: When the pH and/or temperature is varied, the contact angles (CAs) of the dual-responsive materials change reversibly. The general change in trend of wettability is that half of the water CAs are almost all larger than 130° (red backround) and the others are almost all smaller than 20° (blue background).
