Fig. 2

a, e AFM surface morphology images of (a) flat PDMS (Rq = 0.686) and (e) bumpy PDMS pads. b, f SEM low-magnification topographical images and c, g their high magnification images for nanodomain orientations of shear-rolled PS-b-PMMA films at 280 °C with (b, c) flat PDMS pad and (f, g) bumpy PDMS pads. d, h Schematics of the shear-rolling process at the last stage with (d) flat PDMS and (h) bumpy PDMS.
