Core-crosslinked Patchy Micelles of Block Copolymers Containing the Poly(vinyl pyridine) Block |
| 초록 |
Patchy particles can be utilized as building blocks for superstructures. We developed patchy micelles induced from core-crosslinked spherical micelles of diblock copolymers. The crosslinking of the core was critical for the formation of patchy micelle from the spherical micelle. In this study, we synthesized polystyrene-containing block copolymers with poly(2-vinyl pyridine) (P2VP) or poly(4-vinyl pyridine) (P4VP) blocks which can be crosslinked by quaterinization with alkyl or aromatic molecules having two or three halide functional groups. We were able to crosslink the P4VP core in a relatively mild condition, which was utilized to encapsulate nanoparticles. In contrast, crosslinkers with high reactivity were effective to crosslink the P2VP core, from which the number of patches on the micelles was investigated. We also synthesized triblock terpolymers consisting of PS, P2VP, and P4VP to explore the effect of crosslinking of the cores on the formation of patches. |
