Effect The Finalizations Multi Wall Carbon Nanotube on The Characteristics of Polypyrrole Thin Films

Abstract

The nanocomposite (PPy/fMWCNT) is prepared via electrochemical polymerization onto indium tin oxide (ITO) coated glass for pyrrole (Py) monomer with oxalic acid (C2H2O4) and various concentration from functionalized multi wall carbon nanotube fMWCNT (0.01, 0.02) in the 130 mL from distilled water. The structure, morphology and optical properties of thin films were investigated via X-Ray diffraction (XRD), Filed Emission Scanning Electron microscopy (FE-SEM), ultraviolet-visible (UV-VIS) spectroscopy and Fourier Transform Infrared (FT-IR) Spectroscopy. The X-ray diffraction pattern indicates that the prepared thin films are of polycrystalline structure at 2θ= (25, 42)o. The band gap of thin films decreases from 2.4 to 2.09 eV as the fMWCNT increased from 0.01 to 0.02 M, whereas FTIR showing the distinctive bonds of these films
