| Abstract | ||
| Polyaniline (PANI) in Emeraldine salt form was prepared by chemical oxidative polymerization of the appropriate monomeric aniline using two different acid doping (Hydrochloric acid (HCL) and P-Toluene sulfonic Acid (PTSA)) respectively. The prepared samples were characterized by Fourier transform- infrared (FT-IR) spectroscopy; Ultraviolet- Visible (UV-VIS) spectroscopy and X-ray diffraction technique (XRD). The FT-IR and UV-VIS spectroscopy results indicate the doping state of PANi (HCL and PTSA). The crystallinity of the samples was studied in detail by X-ray diffraction technique. The (I-V) characteristic of (PANI) at room temperature, it was showed linear curve close to zero bias indicates that the charge transfer is a straight forward consequence of ohmic behavior, indicating that the measurement was performed in a field independent conductivity region. The scanning electron microscopy (SEM) was used to determine the morphology of the as-prepared nanomaterials. | ||
