Arrangement of the Block Copolymers Microdomains Confined at Hemi-sphere Walls |
초록 |
The arrangement of the microdomains of polystyrene-block-poly(methyl methacrylate) copolymer (PS-b-PMMA) confined at hemi-sphere walls was investigated by scanning and transmission electron microscopy. The hemi-spherical confinement was achieved by using anodic aluminum oxide (AAO) template. The wall surface was modified by thin layers grafted by PS, PMMA, and PS-ran-PMMA copolymer. When the diameter of AAO is commensurate with the bulk lamellar spacing (L0) of PS-b-PMMA, the concentric rings consisting of PS and PMMA are observed. However, the commensurability was not satisfied, we found various interesting morphologies which have not been reported in the literature. The observed microdomain arrangement was compared with theoretical predictions. |
