Large-scale Orientation of Cylindrical Microdomains of Block Copolymers in Thin Films Induced by Unidirectionally Aligned Soft Patterns |
| 초록 |
In this study, we investigate the orientation of cylindrical microdomains of P2VP blocks in the thin films of polystyrene-block-poly(2-vinylpyridine) copolymers (S2VPs) on soft line patterns of poly(tetrafluoroethylene) (PTFE). Unidirectionally aligned soft line patterns of the PTFE are first fabricated by physically rubbing a PTFE bar on flat Si wafer surface at high temperatures closed to its melting points. The thin films of S2VP are spin-coated directly on the soft line patterns followed by solvent-annealing process to induce their self-assembly. Upon solvent-annealing, it is observed that the cylindrical microdomains are oriented perpendicular to direction of the soft line patterns. Finally, the P2VP cylinders are utilized as templates to synthesize nanowires of various metals. |
