Synthesis and characterization of conductive poly(o-anisidine)/talc composite

Abstract

Conductive poly(o-anisidine) (POA)/talc composite was prepared by chemical polymerization of o-anisidine in the presence of talc using ammonium persulfate (APS) as oxidant. The polymerization parameters such as APS/o-anisidine mol ratio, o-anisidine and HCl concentration on the conductivity and POA amount of the POA/talc composite were investigated. The increased microhardness property of the talc particles by the addition of the conducting polymer was examined by micro indentation analysis. The structural, morphological and thermal properties of the composites were analyzed by using FTIR (Fourier transform infrared spectroscopy), XRD (X-ray diffraction), SEM (Scanning electron microscopy), BET (Brunauer-Emmett-Teller) surface area analysis and TGA (Thermogravimetric analysis) techniques.
