Synthesis and characterization of Polyaniline Nanocomposite by Using Several Types of Surfactants in Aqueous Media

Polyaniline (PANI) nanocomposite has been successfully prepared in aqueous media by the chemical polymerization of aniline with ammonium peroxydisulphate as an initiator in the presence of a steric stabilizer such as sodium dodecylbenzenesulfonate (DBSNa), Poly(vinyl pyrrolidone) (PVP), poly(vinyl alcohol) (PVA), poly(ethylene glycol) (PEG) and hydroxypropylcellulose (HPC). The chemical structure, morphology, thermal stability and thermal degradation of the synthesized PANI nanocomposite were studied by different techniques such as fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), X-ray diffraction (XRD) and four-probe. The results revealed that surfactant dispersed uniformly in polyanilin matrix and made a nanocomposite with average crystallite size about 74 nm.
