Preparation And Investigation On Structural, Spectral, Electrical And Magnetic Properties Of Polyaniline Doped By Trifluroacetic Acid In One Step



Authors : Naar Nacira .

Abstract

The aim of the article is to give the electronic properties and delocalized charges as probed by the Electron Paramagnetic Resonance (EPR) spectroscopy of the Polyaniline (PANI) chemically synthesized in one step with the trifluoroacetic acid (TFAA). The amount of doping under these operating conditions was identified by elemental analysis. The structure is investigated by FTIR spectroscopy and the X-rays measurements. The polaronic nature of free carriers is further investigated by UV-visible- NIR and EPR analysis while a value of 12.0 S/m has been measured for the electrical conductivity. The thermal (TGA) and morphological methods were used to investigate the nature of the obtained TFAA-doped PANI.
