A multi‐stage temperature responsive wettable surface composed of poly(N‐isopropylmethacrylamide)‐block‐poly(N‐isopropylacrylamide)(PNIPMAM‐b‐PNIPAm) is fabricated on a structure‐enhanced silicon substrate by atom transfer radical polymerization. Detailed AFM investigation indicates that the adhesion force on the prepared surface decreases with the increase of temperature, which shows a three‐stage force rundle consistent with the change of surface wettability.
