Abstract

• Conductive composites include any composite having significant electrical conductivity. An electrically conductive filler such as carbon-based materials like graphene when added to insufficient quantities of a polymeric resin, a conductive composite is formed. This research focus on the preparation of the conductive polymer using the organic copolymer and the inorganic particles. Copolymer P(Py-co-FPy) films were prepared by chemical copolymerization of pyrrole (Py) and pyrrole -2carboxaldehyde (FPy) in the trifluoroacetic acid (TFA) catalyst and chloroform (CHCl3) solvent. As the inorganic component, reduced graphene oxide (rGO) was synthesized by chemical reduction method. In preparation of P(Py-co-FPy)-rGO composite films the different grams of rGO powders are incorporated into the copolymer matrices by ex-situ chemical copolymerization through spin coating technique. The structural and electrical properties of copolymer and composite films were characterized by Fourier transform infrared spectroscopy (FTIR) and the conductivities of the composite films are increased with the concentration of inorganic particles. It is found that the conductivities of P(Py-co-FPy)-rGO (0.3 g) composite film are greater than those of pure copolymer P(Py-co-FPy) film.
