Structural effects of TiO2 nanopores well-arranged via block copolymer self-assembly |
| 초록 |
Nanostructured TiO2 has attracted intensive scientific interest due to its unique properties caused by the confinement effects and large specific surface area which are key parameters in enhancing the effectiveness of TiO2 in various applications. A simple route to produce nano structured titania based on template approach has been investigated in this work. Polystyrene-block-poly(ethylene oxide) copolymer and PS nanoparticles are used as a structure-directing agent, and titanium precursor is coupled with a matrix of block copolymer and nanoparticles through a hydrolysis, and condensation process. After coated on the substrate, they were calcined at high temperature to remove organic compounds. As an application, nanostructured TiO2 obtained in our work was applied for the frictional layer of triboelectric nanogenerators. The performance of triboelectric nanogenerator was examined with the variation of TiO2 nanostructures and their structural effects were systematically investigated. |
