AFM topographies of (a) PF14-b-Piso10, (b) PF14-b-Piso20, (c) PF14-b-Piso60 and (d) PF14-b-Piso100 thin films. (e) One-dimensional GISAXS profile (qy scan at qz=0.027 Å−1) of PF14-b-Pison thin films. All of the block copolymer thin films were annealed at 100 °C for 2 h. AFM, atomic force microscopy; GISAXS, grazing-incidence small-angle X-ray scattering; PF, poly[2,7-(9,9-dihexylfluorene)]; Piso, poly(pendent isoindigo).
