Size Control and Registration of Nano-structured Thin Films by Cross-linkable Unit |
| 초록 |
In this study, a simple route to control the microdomain size in PS-b-PMMA by varying the amount of cross-linkable BCB unit is presented. PS-b-PMMA, with reactive BCB functionality in the PS block was synthesized by reversible addition fragmentation chain transfer (RAFT) polymerization. Upon annealing at elevated temperatures, the BCB group undergoes a facile intra- and/or inter-molecular cross-linking reaction by ring opening, leading to robust thermoset, nano-structured thin films. These structures were probed by TEM and GISAXS 4C2 beam-line at the Pohang Accelerator Laboratory (PAL). Remarkable advantage of the cross-linkable PS-b-PMMA thin films is their insolubility when the samples are cross-linked at higher temperature (250 ℃), which allows their subsequent use in further processes such as the fabrication of 3-dimensional multi-layered arrays, leading to a propagation of the orientation and ordering of the thin film over large distances.
