제목 Perpendicularly oriented high-density cylindrical microdomains in thin films of block copolymer binary blends with hydrogen bonding
초록 Block copolymers with various microdomains have investigated for various nanolithography applications. In general, hexagonally packed cylindrical microdomains have been found where the volume fractions of cylinder blocks are about from 0.2 to 0.35. However, it is possible to create cylindrical microdomains with f > 0.5 by using strong associative interactions between chains. In this study, poly(styrene) based block copolymers containing poly(vinyl pyridine) or poly(hydroxystyrene) were blended, and inverted cylindrical microdomains were observed by transmission electron microscope and small-angle X-ray scattering. The structures were obtained in thin films with perpendicular alignment by solvent vapor annealing and confirmed by atomic force microscopy
