A Closer Look at the Electrical Properties of Al2O3-Embded Polypyrrole

Abstract

In the present work, a simple chemistry-based polymerization process was utilized to produce clean and Al₂O₃ nanoparticle-doped polypyrrole-based samples using three different Al₂O₃ doping dosages. The prepared samples were characterized using a range of techniques. The X-ray diffraction spectra of the produced samples reveal that they are quasi-crystals. The Fourier transformation infrared spectroscopy of these samples reveals the various required fundamental bands, validating the synthesis of the expected samples. Field emission scanning electron microscopy shows the morphology of the produced materials. The thermal properties of the produced samples were analyzed using thermal gravimetric analysis. Furthermore, the electrical properties of the produced samples were investigated at temperatures ranging from 293 to 393 K. The generated samples' conductivity rises with temperature, suggesting that they are semi-conducting.
