Optical micrographs illustrating the morphology of the PMMA-air interface when the annealing temperature was 180 °C. In image sets 1 and 2, PMMA Mw = 10 kg/mol (3.1 × 103 Pa s) and 350 kg/mol (5.51 × 108 Pa s)51,52,53, respectively, when h PMMA  = 35 ± 2 nm and h PS  = 174 ± 5 nm. Images (A–D) in both the sets correspond to PS Mw = 4 kg/mol, 13 kg/mol, 31 kg/mol, and 2000 kg/mol, respectively. The size of the bar is 40 µm.
