제목 Hybrid Metal/Semiconductor Nanostructures with Tunable Morphologies in Thin Films of Block Copolymers
초록 Nanostructured TiO2 materials have attracted a great deal of attention due to their widespread applications in photocatalysts and elements in photovoltaic and light emitting devices, etc. In order to enhance the performance, numerious attempts have been carried out in terms of controlling and optimizing the composition, shape and size. In this study, we suggest simple strategies to fabricate hybrid Au/TiO2 nanostructures with controlled morphology based on cooperative sol-gel chemistry and block copolymer self-assembly. By controlling the mixing protocol of the precursor solutions, we suggest that ordered arrays of 0-/1-D hybrid Au/TiO2 nanostructures could be obtained as well as non-periodic ones with chaotic morphologies. Potential functions will be explored in correlation of the nanostructures for target specific applications.
