Dual nature, self oxidized poly(o-anisidine) functionalized multiwall carbon nanotubes composite: Preparation, thermal and electrical studies

Poly(o-anisidine) (POAS)/silverized multiwall carbon nanotubes (POAS-MWCNTs/Ag) composite was prepared by adsorption of POAS on the surface of MWCNTs by solution method. This research demonstrated that it was possible to metalized MWCNTs and uses a polymer as a substitute for polyaniline (PANI) to synthesize MWCNTs/conducting polymer nanocomposites by one-step easy mixing of solutions. The resulting composite was characterized using SEM: TGA and fourier transform infrared spectroscopy (FTIR), X-ray spectroscopy. The electrical resistivity of the composites was studies and it was found unusually higher conductivity than that of pure POAS and MWCNTs and it was 5 S/cm. All the results demonstrated a facile route to the synthesis of POAS-MWCNTs/Ag composites, possessing good electrical conductivity and outstanding thermal stability at high temperature.
