Abstract Chemically switched friction nano-fibrillar surfaces (SiNWAs-PSPMA & SiNWAs-PMAA arrays) can be constructed by finely decorating ordered Si nanowire arrays with responsive polymer brushes. As expected, these surfaces sense humidity or pH smartly and show reversible friction switching, based on swelling and shrinking of the polymer brushes, which is successfully monitored by AFM in liquid media. © 2014 WILEY-VCH Verlag GmbH & Co.
