Synthesis of Well-Defined Bottle Brush PS-b-PMMA and Their Large Domain Self-Assembly in Thin Films |
| 초록 |
Large domain self-assembly of ultra-high molecular weight block copolymers is very difficult because their mobility is too slow to reach the thermodynamically equilibrated state. To circumvent this problem, we paid our attention to the use of bottle brush block copolymers. They are comprised of a linear polymer backbone and side polymer brushes. Since the side brushes are densely attached to the backbone, there is significant steric congestion, which makes the backbone highly stretched and rigid. Here we report the first “graft-through” synthesis of well-defined bottle brush PS-b-PMMA and their self-assembly into the perpendicular lamellae (~80 nm) in thin films by the only thermal annealing process. We have employed both anionic polymerization and ring-opening metathesis polymerization (ROMP) through the following process (1) initiator preparation, (2) anionic polymerization for brushes, (3) post polymerization-modification of an end group, and (4) ROMP based on the Grubbs catalyst. |
