Phase Behavior of Binary Blend of AB2 Miktoarm Star and AC Block Copolymers Having Hydrogen Bonding |
| 초록 |
The binary blend of block copolymers containing poly(2-vinylpyridine) and poly(hydroxystyrene) forms hydrogen bonding between the blocks, and could show unexpected microdomains that cannot be obtained in neat block copolymer. In this study, we prepared the binary blend of asymmetric polystyrene-block-[poly(2-vinylpyridine)]2 (as-PS-b-P2VP2) and polystyrene-block-poly(hydroxylstyrene) (as-PS-b-PHS) copolymers. Miktoarm star copolymers were synthesized by anionic coupling with polystyrene having two halogen end groups and PS-b-PHS were prepared via the hydrolysis reaction of PS-b-poly(4-tert-butoxy styrene) copolymers. The blends showed cylindrical microdomains due to the interface curvature change by both favorable hydrogen bonding between P2VP and PHS blocks and miktoarm structure. |
