제목 | Phase Behavior and Thin Film Morphology of Star-shaped PS-block-PMMA Copolymers |
초록 | Star-shaped 18 arm poly(methyl methacrylate)-block-polystyrene copolymers ((PMMA-b-PS)18) were synthesized by using α-cyclodextrin (α-CD) as a core of the star-shape. Morphology of star-shaped block copolymers were characterized by TEM and small angle X-ray scattering. We also investigated thin film morphology of (PMMA-b-PS)18 exhibiting lamellar and PMMA cylindrical nanodomains. When a thin film was spin-coated on a substrate, vertically aligned lamellar and cylindrical nanodomains were obtained without any pre- or post-treatment. Moreover, vertical orientations are observed on versatile substrates, for instance, semiconductor (Si, SiOx), metal (Au), PS or PMMA-brushed substrate, and a flexible polymer sheet of polyethylene naphthalate (PEN). |
