제목 | Synthesis of conjugated polymer - mesoporous TiO2 nanocomposite particle and thin film |
초록 | Synthesis of conjugated polymer-TiO2 nanocomposites has been attracted for their useful applications in optoelectronic devices, such as solar cells, electrochromic devices, light-emitting diodes, and charge-storage devices, which make a heterojunction between organic and inorganic semiconductors where charge transfer occurs. In this study, we propose a new method to obtain a porous nanocomposite of conjugated polymer and TiO2 by a direct polymerization of conjugated polymer in the mother solution of mesoporous TiO2. We prepared two types of nanocomposites, core-shell nanoparticles of polymethineimine and mesoporous TiO2, and nano-sized polypyrrole embedded mesoporous TiO2 thin film. Core-shell nanoparticles of polymethineimine and mesoporous TiO2 were synthesized using TiCl4 as a catalyst for the polymerization of polymethineimine and as a precursor of TiO2. And nano-sized polypyrrole embedded mesoporous TiO2 thin films were synthesized using sonochemical polymerization of pyrrole in the mother solution of mesoporous TiO2 thin film. |
