AFM topographic images obtained using the intermittent contact mode of PSt_60%-b-PDEAEM_40% thin films prepared from a 1% w/w toluene solution over mica substrate at a spinning velocity of 5000 rpm: (a) directly after spin coating (RMS = 1.09 nm) and after UV irradiation ( nm) for different times: (b) 15 min (RMS = 3.53 nm) and (c) 30 min (RMS = 4.07 nm).
