| 논문초록 | This study presents a binary blend of block copolymers that fabricates inverted cylindrical microdomains. This blend system consists of polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) and polystyrene-block-poly(hydroxylstyrene) (PS-b-PHS). Hydrogen bond interactions occur between P2VP and PHS and affect the interface curvature and the phase behavior of binary blends. The blends formed hexagonally-packed cylindrical microdomains and the volume fraction of the cylinder parts was ＞ 0.6. The morphology of blends was unexpected in comparison with usual block copolymer systems and achieved high-density HEX cylindrical patterns. |
