Synthesis of Fe 3+-Dopped PANI Conductive Nanomaterials via Interfacial Polymerization

Article Preview

A series of Fe3+-dopped polyaniline (Fe3+/PANI) nanomaterials with different morphologies and a higher conductivity were successfully synthesized using a simple and static interfacial polymerization by using FeCl3 as both oxidant catalyst and dopant. The effect of surfactants CTAB and SDS and the concentration of FeCl3 on the morphology and conductivity of Fe3+/PANI nanomaterial were investigated. The samples were characterized by Transmission Electron Microscopy (TEM), SDY-4 probes conductivity meter, X-ray Diffractometry (XRD), Energy dispersive spectroscopy (EDS) and Fourier transform infrared (FT-IR) spectroscopy techniques. TEM’s results showed that their morphologies changed with the type of the surfactant and the concentration of FeCl3. Introducing surfactants CTAB and SDS into Fe3+/PANI remarkably improved the conductivity of the material. The conductivities of CTAB/Fe3+/PANI and SDS /Fe3+/PANI nanomaterials were respectively about 4.8×10-2 and 1.3×10-2 S/cm while the conductivity of Fe3+/PANI was found to be 1.5×10-4 S/cm. The different morphology and high conductivity may be ascribed to the mutual effects of the surfactant and oxidant.
