Cylindrical and lamellar nanostructures of block copolymers in thin films can be perpendicularly oriented to the plane of the films by neutralizing surfaces of the substrates. These perpendicularly oriented nanostructures can be utilized as guiding templates to generate directed patterns of functional materials. In this study, perpendicularly oriented cylindrical and lamellar structures of polystyrene-poly(methyl methacrylate) (PS-PMMA) diblock copolymers were synthesized on metal oxide substrates by transferring the polymer nanostructures from silicon oxide substrates. After PMMA block was selectively removed from the polymer films by wet etching, the remaining PS nanostructures were used as templates for the controlled hydrothermal growth of metal oxides. By using the PS cylindrical and lamellar templates, we could control the shape and dimension of metal oxide nanostructures. |
