【 摘 要 】

Conducting polymer provides an intriguing type of environment for various inorganic structures resulting in the generation of exciting properties in the composite owing to the mutual interactions between the two and this provides interesting dimensions for the development of new multifunctional devices. ZrO2 ceramic is one of the most investigated materials for its outstanding mechanical properties ionic, conduction properties and due to its high oxygen ion conduction. In order to achieve novel properties of ZrO2 nanoparticles, nanocomposites of ZrO2 with Polypyrrole (PPy) were prepared through in-situ method using ZrO2/pyrrole dispersions. Firstly, ZrO2 nanoparticles were synthesized by co-precipitation method and then embedded in pyrrole solution for polymerization. The structural and optical properties of ZrO2/PPy nanocomposites were investigated comprehensively by X-Ray diffraction (XRD), UV-visible spectroscopy and Fourier-transform infrared spectroscopy (FTIR). XRD and FTIR highlight the presence of tetragonal phase of ZrO2 nanoparticles in nanocomposites, whereas UV-Visible and PL spectra indicate the presence of different electronic levels.
