【 摘 要 】

Polyaniline (PANI) was synthesized by chemical oxidative polymerization of aniline using ammonium persulphate as an oxidant in acidic aqueous medium. Cobalt chloride hexahydrate (CoCl₂â‹�??6H₂O)-doped PANI composite was synthesized by in-situ oxidative polymerization process by using various concentrations of CoCl₂. Its chemical, structural and morphological properties were examined by X-ray diffraction, energydispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and field-emission scanning electron microscopy techniques. These results confirmed the successful formation of PANI and CoCl₂-doped PANI nanocomposites. The morphology of CoCl₂-doped PANI nanocomposite was found to be spherical in nature. The dielectric properties were examined using LCR-HITESTER in the frequency range 50 Hzâ€�??5 MHz. The optical properties were examined by UVâ€�?�visible spectroscopic techniques in the wavelength range of 200â€�??800 nm. The high dielectric properties and alternating current conductivity of the composite was studied in the temperature range 313â€�??373 K. It was found that the synthesized polymeric nanocomposite owned fairly suitable dielectric and optical properties for its application in actuators, conductive paints and for many other purposes.
