Abstract
Polyaniline (PANI) nanocomposite has been successfully prepared in aqueousmedia by the chemical polymerization of aniline with ammonium peroxydisulphateas 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). Thechemical structure, morphology, thermal stability and thermal degradation of thesynthesized PANI nanocomposite were studied by different techniques such asfourier transform infrared spectroscopy (FTIR), scanning electron microscope(SEM), X-ray diffraction (XRD) and four-probe. The results revealed that surfactantdispersed uniformly in polyanilin matrix and made a nanocomposite withaverage crystallite size about 74 nm.
