Frustrated Block Copolymer in the Hemi-Sphere Geometry |
| 초록 |
The arrangement of the microdomains in block copolymers changes significantly when they are confined at certain geometric constraint. Although many works have been reported on microdomain arrangement at one-dimension, two-dimension, and three-dimension confinement, the hemi-spherical geometry has been never employed. Here, we study, via scanning and transmission electron microscopy, the arrangement of the microdomains of symmetric polystyrene-block-poly(methyl methacrylate) copolymer (PS-b-PMMA) confined at hemi-sphere walls. This was prepared by using anodic aluminum oxide template. The inner wall surface of the hemi-sphere was further modified by three different brush layers: (1) PS, (2) PMMA, and (3) neutral brushes on PS and PMMA. Interesting morphologies not reported previously was fisrt observed. The microdomain arrangement hemi-sphere confinement was explained theoretically. |
