AFM images of the PMMA/PUA blended films with different total concentrations. The cured PUA domains and the PMMA domains before the THF treatments for (a) 10 wt%, (b) 15 wt%, and (c) 20 wt% blended solutions, and the cured PUA domains remaining after the THF treatments for (d) 10 wt%, (e) 15 wt%, and (f) 20 wt% blended solutions. The height profiles are shown in insets.
