Conducting polymers, possessing a conjugated π-electron system, have widely been investigated in various fields such as sensors, field-effect transistors and solar cells because of their exceptional electrical and optical properties. To improve and extend their properties and functions, nanocomposites of conducting polymers and inorganic materials have been intensively investigated in that their physical and chemical properties could be adjusted by selecting the type of the polymer and inorganic materials. In this work, we have fabricated nanocomposites of polyanline and TiO2 by vapor phase polymerization and chemical oxidative polymerization. TiO2 nanostructures were fabricated by the combination of sol-gel reaction and block copolymer self-assembly, and then polymerization of polyaniline was carried out using TiO2 as a substrate. Consequently, PANI were selectively deposited on oxidant region to generate well-defined nanopatterns of conducting polymers and nanocomposites. |
