Inverted Cylinder Structures from AB/AC Diblock Copolymer Blends with Hydrogen Bonding |
초록 |
Block copolymers with various microdomains have investigated for various nanolithography applications. In general, hexagonally packed cylindrical microdoains have been found where the volume fractions of cylinder blocks are about from 0.2 to 0.35. This study presents a binary blend of block copolymers interacting hydrogen bonding to fabricate inverted cylinder structures by self-assembly. This blend system consists of polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) and polystyrene-block-poly(4-hydroxystyrene) (PS-b-PHS). The hydrogen bonding between P2VP and PHS change the interface curvature. The blends exhibited inverted HEX cylindrical microdomains having the volume fraction of cylinders was more than 0.6 and investigated by transmission electron microscopy and small angle X-ray scattering. The thin films with vertically oriented inverted cylinder patterns were prepared by solvent vapor annealing. |
