Fig. 3: Characterization of surface structures derived from three chemically distinct binary BMAs at two stoichiometries each.
From: Film surface assemblies from chemically distinct block copolymer micelles
Top surface SEM image derived segmentations of binary a, b ISV121 + ISVO165, c, d ISVO165 + SVPS53, and e, f ISV121 + SVPS53 BMAs evaporated for 80 s. Red, blue, green, and magenta pixels, respectively, represent ISV121, ISVO165, SVPS53 pores, and the solid matrix. Compositions by wt. as labeled following the same color code. The larger non-porous spaces in (a and b) are a result of image processing (“Methods”). g–l BD simulation box surface snapshots of binary BMAs at the labeled wt. compositions. Each pair of snapshots (e.g, g and h) reflects the same simulation time (“Methods”). FFT image analysis of 75:25 m ISV121: ISVO165, n ISVO165: SVPS53, and o ISV121: SVPS53 samples (by wt.) was performed after the populations were split (“Methods”). FFT traces from split populations are sandwiched between those of the corresponding pure samples (top and bottom in m–o). Vertical reference lines—corresponding to first four peak positions of the uppermost trace—serve as visual aids.
