Highly oriented thin-film Microdomain patterns of ultrahigh molecular weight block copolymers via directional solidification of a solvent
Excellent control of the thin-film microdomain orientation of lamellar-(LAM) and cylinder-(CYL) forming ultrahigh molecular weight block copolymers has been obtained over a large area via directional solidification of a crystallizable solvent. 3D optical imaging of the microdomains via laser scanning confocal microscopy (see figure) directly show an intriguing orientation of the intermaterial dividing surfaces (IMDSs).
