Implementation of Bottlebrush Polymer in Inducing Perpendicular Orientation of High-χ Block Copolymers on Thin Film |
| 초록 |
Inducement of the perpendicular orientation of high-χ block copolymer (BCP) on thin film has been of utmost importance for its applicability to next-generation nanolithography. In this study, we present inducement of high- χ BCP (PS-b-PMAA) perpendicular to the substrate without any surface treatment by implementing bottlebrush polymer(BBP) with random copolymer side chains. Architecture difference between bottlebrush and linear polymer leads to the air and substrate interfaces be entropically favorable to BBP and make BBPs neutralize the interfaces. Synthetic methods for BBPs are RAFT followed by ROMP to from BBPs with random copolymer side chains. BBPs with PS-r-PtBMA side chains go through hydrolysis reactions and are converted to BBPs with PS-r-PMAA side chains. Used as additives, BBPs segregated towards the surface and the substrate after going through the spin coating and thermal annealing. Perpendicular orientation of PS-b-PMAA is proved by SEM and GI-SAXS. |
