Synthesis of conducting polyaniline/ZrO2 composites via in-situ γ-radiolysis oxidative polymerization |
| 초록 |
Zirconia (ZrO2) particles were synthesized by sol-gel method and formation of hybrid composites with conducting polyaniline [PANI] via in situ gamma radiation-induced chemical oxidative polymerization method. Transmission electron microscopy (TEM) confirmed the core-shell morphology in which ZrO2 particles were well dispersed in the PANI matrix. The incorporation of ZrO2 in the composite was endorsed by Fourier transform infrared spectroscopy (FT-IR). UV-visible spectra of the diluted colloid dispersion of composite particles were similar to those of the neat copolymer. Thermogravimetric analysis revealed that the composites have a higher degradation temperature than PANI. X-ray diffraction (XRD) patterns of PANI/ ZrO2 composites were similar to that of the PANI alone, indicating that no additional crystalline order or chain arrangement had been introduced. Room-temperature conductivity of composites decreases with an increasing fraction of ZrO2. |
