Electrophysical properties of composite materials based on graphene oxide and polyaniline

Keywords: Composite materials, Polyaniline, Graphene oxide, Specific conductivity, Band gap


The Hall method was used to study the electrical characteristics of composite materials based on polyaniline (PANI), graphene oxide (GO), and manganese. A comparison of these characteristics of GO-PANI and GO-PANI-Mn composite systems with GO and PANI monomaterials was carried out.

It was demonstrated that the electrical conductivity of composites was significantly higher than that of monomaterials and was determined by the charge carrier mobility.

Based on UV-visible and IR spectroscopy data, it was shown that the optical band gap (Eg) of the GO-PANI composite increased with the addition of metal, but decreased compared to PANI; the shift of characteristic vibrations to lower frequencies indicated a covalent interaction of the GO-PANI composite with manganese cations
