Among the various organic-inorganic nanocomposites, conjugated polymer-TiO2 nanocomposite is one of the most interesting nanocomposite types due to the useful application associated with its unique optical, electronic, and optoelectronic properties. In this study, we prepared polymethineimine-nanoporous TiO2 core-shell nanoparticles by adding s-triazine to the mother solution of nanoporous TiO2. It has a large interface area between polymer and TiO2, and large surface area due to the nanoporous inorganic shell. So, it could be applicable to photovoltaic devices and sensors by making colloidal aggregated film, and so on. In this work, mixture of two triblock copolymers, Pluronic P123 and Pluronic F127, was used as a template material of nanoporous inorganic shell, and TiCl4 was used both as a catalyst for polymerization of polymethineimine and a precursor material of TiO2. |
