The template approach to nanostructured organic/inorganic hybrid materials has been the subject of numerous studies because of their many useful optical, electrical, and photocatalytic properties. In many cases, the morphology and crystallinity of these nanostructured materials significantly affect their performance, and it is very crucial to effectively control the structure and morphology of such hybrid materials. In this study, titania-block copolymer hybrids have been synthesized with variable morphologies by spin-coating based on the directing agent, polystyrene-block-poly(ethylene oxide) block copolymers dissolved in 1,4-dioxane and precursor, titanium isopropoxide. To remove organic compound and generate crystalline structure of titania, it has been calcined at high temperature. The structure and morphology were systematically examined as a function of relative composition of components via AFM and SEM. |
