Synthesis, Characterization and AC-Impedance Spectroscopic Studies on Interfacial Synthesis of Pani / PEG Nanocomposite

摘要

Polyaniline/PEG nanocomposite was prepared via a interfacial polymerization method by using ammonium peroxedisulphate as an oxidizing agent. A mechanism of formation of polyaniline-polyethylene glycol has been suggested in which polyethylene glycol works as a medium for diffusion-limited growth of the components during their precipitation. On studied AC impedance spectroscopy Studied, it was found that the electrical conductivity of interfacialy synthesized PAni-PEG composite 3.96 x 10^-2 Scm^-1 was slightly low than bulk PAni (1.87 x 10^-1 Scm^-1) due to formation of nanostructures. These materials were characterized by FTIR, UV- Visible, XRD, SEM and AC-impedance spectroscopy.
