FIG. 1.

Plan-view scanning electron micrographs of binary blends of diblock copolymers on chemically nanopatterned neutral polymer brushes. The period of the underlying chemical nanopattern increases from 40 to from left to right in increments of . From top to bottom the rows contain micrographs of LO48, LB44, and LB41. The micrographs all image areas.

FIG. 2.

Plan-view scanning electron micrographs of binary blends of diblock copolymers on chemically nanopatterned polystyrene brushes. The period of the underlying chemical nanopattern increases from 40 to from left to right in increments of . From top to bottom the rows contain micrographs of LO48, LB44, and LB41. The micrographs all image areas.

Image of FIG. 3.
FIG. 3.

Azimuthally averaged power spectra of 2D-FFTs of the scanning electron micrographs of block copolymer domains on chemically nanopatterned polystyrene and chemically nanopatterned neutral brushes. Black lines are for the block copolymer domain behavior on patterned polystyrene brushes; gray lines are for the block copolymer domain behavior on patterned neutral brushes. (a) LO48, (b) LB44, and (c) LB41. Substrate pattern periods are presented at the right side of the graphs. Spectra are offset for clarity.
