Patchy Micelles of PS-b-P2VP Diblock Copolymers Synthesized by RAFT Polymerization |
| 초록 |
We recently reported patchy micelles and their supracolloidal chains mainly using PS-b-P4VP diblock copolymers. These supracolloidal chains were effectively functionalized by modifying the P4VP block with fluorophores and nanoparticles. In this presentation, we examined patch formation on spherical micelles of PS-b-P2VP diblock copolymers which were synthesized by RAFT polymerization. We changed the block ratio of PS to P2VP by adding the second block of PS with various molecular weights to the first block of P2VP having the same molecular weight. Spherical micelles were then induced in a selective solvent of the P2VP block and patches were formed on the micelles by changing the solvent preferable to the core but still compatible with the corona. The number of patches on the micelles depending on the block ratio of copolymers was characterized primarily by transmission electron microscopy. |
