Abstract

Polyaniline (PANI) has drawn demanding attention because of its inimitable conductive properties, ease of doping, easy synthesis, remarkable environmental stability, and versatile applications in various fields. The aim of this research is to synthesis PANI, explore and enhance its electrical properties. Besides PANI, binary PANI/carbon nanofiber (CNF) and ternary hybrid PANI/CNF/Cu composites were synthesized, and their thin films on fluorine tin oxide (FTO) coated glass were fabricated by layer by layer deposition. PANI polymer was synthesized by chemical oxidative polymerization (COP) method. To stabilize the conductive form of PANI, the whole reaction is conducted in an acidic medium. Since the polymerization process is exothermic, an ice bath is used to propagate the reaction. For the synthesis of PANI/CNF and PANI/CNF/Cu composites, appropriate proportions of CNF suspension and CNF suspension/Cu nano particles were dispersed properly in aniline. For films fabrication, fluorine doped tin oxide (FTO) coated glass substrates were dipped repeatedly into the solution. The chemical composition, crystal structure, and electrical properties of the prepared composites and films were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Impedance analysis (IA) respectively. The electrical properties i.e. conductivity, conductance and capacitance of the prepared bare polymer to binary and ternary composites increased significantly. The results coming from the experiment revealed that fabricated PANI/CNF/Cu thin film on FTO glass showed much higher electrical properties than that of PANI/CNF and PANI thin films on FTO glass.
