Hierarchical Structures in Thin Films of Polymethacrylate DiblockCopolymer grafted with POSS Moieties |
초록 |
The morphological structures in thin films of a diblock copolymer of methyl methacrylate and polyhedral oligomeric silsesquioxane (POSS) functionalized methacrylate (PMMA-b- PMAPOSS) with a volume ratio of 13/87 were investigated in detail by using synchrotron grazing incidence small and wide-angle X-ray scattering (GISAXS and GIWAXS). Thin films of this diblock copolymer were found to undergo phase-separation during solvent-annealing with carbon disulfide and post thermal annealing. The cylinders of PMMA blocks are induced to form in the diblock copolymer films by solvent-annealing and are hexagonally packed in the PMAPOSS matrix, in which the cylinders are oriented vertically with respect to the film plane. And post thermal annealing process induces aggregation of the POSS moieties, which results in the formation of crystals with an orthorhombic lattice unit cell. |
